Struct rhai::Engine

pub struct Engine { /* fields omitted */ }

Rhai main scripting engine.

use rhai::Engine;

let engine = Engine::new();

let result = engine.eval::<i64>("40 + 2")?;

println!("Answer: {}", result);  // prints 42

Currently, Engine is neither Send nor Sync. Turn on the sync feature to make it Send + Sync.

Implementations

impl Engine

Engine public API

pub fn register_type<T: Variant + Clone>(&mut self)

Register a custom type for use with the Engine. The type must implement Clone.

Example

#[derive(Debug, Clone, Eq, PartialEq)]
struct TestStruct {
    field: i64

    fn new() -> Self                    { TestStruct { field: 1 } }
    fn update(&mut self, offset: i64)   { self.field += offset; }
}

use rhai::{Engine, RegisterFn};

let mut engine = Engine::new();

// Register the custom type.
engine.register_type::<TestStruct>();

engine.register_fn("new_ts", TestStruct::new);

// Use `register_fn` to register methods on the type.
engine.register_fn("update", TestStruct::update);

assert_eq!(
    engine.eval::<TestStruct>("let x = new_ts(); x.update(41); x")?,
    TestStruct { field: 42 }
);

pub fn register_type_with_name<T: Variant + Clone>(&mut self, name: &str)

    fn new() -> Self { TestStruct { field: 1 } }
}

    engine.eval::<String>("let x = new_ts(); type_of(x)")?,
    "rust_out::TestStruct"
);

engine.register_type_with_name::<TestStruct>("Hello");

// Register methods on the type.
engine.register_fn("new_ts", TestStruct::new);

assert_eq!(
    engine.eval::<String>("let x = new_ts(); type_of(x)")?,
    "Hello"
);

pub fn register_iterator<T: Variant + Clone>(
    &mut self,
    f: fn(_: Dynamic) -> Box<dyn Iterator<Item = Dynamic>>
)

Register an iterator adapter for a type with the Engine. This is an advanced feature.

pub fn register_get<T, U>(
    &mut self,
    name: &str,
    callback: impl Fn(&mut T) -> U + SendSync + 'static
) where
    T: Variant + Clone,
    U: Variant + Clone, 

Register a getter function for a member of a registered type with the Engine.

The function signature must start with &mut self and not &self.

struct TestStruct {
    field: i64
}

impl TestStruct {
    fn new() -> Self                { TestStruct { field: 1 } }

    // Even a getter must start with `&mut self` and not `&self`.
    fn get_field(&mut self) -> i64  { self.field }
}

use rhai::{Engine, RegisterFn};

let mut engine = Engine::new();

// Register the custom type.
engine.register_type::<TestStruct>();

engine.register_fn("new_ts", TestStruct::new);

// Register a getter on a property (notice it doesn't have to be the same name).
engine.register_get("xyz", TestStruct::get_field);

engine.register_fn("new_ts", TestStruct::new);

// Register a setter on a property (notice it doesn't have to be the same name)
engine.register_set("xyz", TestStruct::set_field);

// Notice that, with a getter, there is no way to get the property value
assert_eq!(
    engine.eval::<TestStruct>("let a = new_ts(); a.xyz = 42; a")?,
    TestStruct { field: 42 }
);

pub fn register_get_set<T, U>(
    &mut self,
    name: &str,
    get_fn: impl Fn(&mut T) -> U + SendSync + 'static,
    set_fn: impl Fn(&mut T, U) + SendSync + 'static
) where
    T: Variant + Clone,
    U: Variant + Clone, 

Shorthand for registering both getter and setter functions of a registered type with the Engine.

All function signatures must start with &mut self and not &self.

Example

impl TestStruct {
    fn new() -> Self                        { TestStruct { field: 1 } }
    fn get_field(&mut self) -> i64          { self.field }
    // Even a getter must start with `&mut self` and not `&self`.
    fn set_field(&mut self, new_val: i64)   { self.field = new_val; }
}

use rhai::{Engine, RegisterFn};

let mut engine = Engine::new();

// Register the custom type.
engine.register_type::<TestStruct>();

engine.register_fn("new_ts", TestStruct::new);

// Register a getter and a setter on a property
// (notice it doesn't have to be the same name)
engine.register_get_set("xyz", TestStruct::get_field, TestStruct::set_field);

assert_eq!(engine.eval::<i64>("let a = new_ts(); a.xyz = 42; a.xyz")?, 42);

pub fn register_indexer<T, X, U>(
    &mut self,
    callback: impl Fn(&mut T, X) -> U + SendSync + 'static
) where
    T: Variant + Clone,
    U: Variant + Clone,
    X: Variant + Clone, 

Register an indexer function for a registered type with the Engine.

The function signature must start with &mut self and not &self.

Example

#[derive(Clone)]
struct TestStruct {
    fields: Vec<i64>
}

impl TestStruct {
    fn new() -> Self                { TestStruct { fields: vec![1, 2, 3, 4, 5] } }

    // Even a getter must start with `&mut self` and not `&self`.
    fn get_field(&mut self, index: i64) -> i64 { self.fields[index as usize] }
}

use rhai::{Engine, RegisterFn};

// Register the custom type.
engine.register_type::<TestStruct>();

engine.register_fn("new_ts", TestStruct::new);

// Register an indexer.
engine.register_indexer(TestStruct::get_field);

assert_eq!(engine.eval::<i64>("let a = new_ts(); a[2]")?, 3);

pub fn compile(&self, script: &str) -> Result<AST, ParseError>

Compile a string into an AST, which can be used later for evaluation.

Example

use rhai::Engine;

let engine = Engine::new();

// Compile a script to an AST and store it for later evaluation
let ast = engine.compile("40 + 2")?;

for _ in 0..42 {
    assert_eq!(engine.eval_ast::<i64>(&ast)?, 42);
}

pub fn compile_with_scope(
    &self,
    scope: &Scope,
    script: &str
) -> Result<AST, ParseError>

Compile a string into an AST using own scope, which can be used later for evaluation.

The scope is useful for passing constants into the script for optimization when using OptimizationLevel::Full.

Example

use rhai::{Engine, Scope, OptimizationLevel};

let mut engine = Engine::new();

// Set optimization level to 'Full' so the Engine can fold constants
// into function calls and operators.
engine.set_optimization_level(OptimizationLevel::Full);

// Create initialized scope
let mut scope = Scope::new();
scope.push_constant("x", 42_i64);   // 'x' is a constant

// Compile a script to an AST and store it for later evaluation.
// Notice that `Full` optimization is on, so constants are folded
// into function calls and operators.
let ast = engine.compile_with_scope(&mut scope,
            "if x > 40 { x } else { 0 }"    // all 'x' are replaced with 42
)?;

// Normally this would have failed because no scope is passed into the 'eval_ast'
// call and so the variable 'x' does not exist.  Here, it passes because the script
// has been optimized and all references to 'x' are already gone.
assert_eq!(engine.eval_ast::<i64>(&ast)?, 42);

pub fn compile_scripts_with_scope(
    &self,
    scope: &Scope,
    scripts: &[&str]
) -> Result<AST, ParseError>

When passed a list of strings, first join the strings into one large script, and then compile them into an AST using own scope, which can be used later for evaluation.

The scope is useful for passing constants into the script for optimization when using OptimizationLevel::Full.

Note

All strings are simply parsed one after another with nothing inserted in between, not even a newline or space.

Example

use rhai::{Engine, Scope, OptimizationLevel};

let mut engine = Engine::new();

// Set optimization level to 'Full' so the Engine can fold constants
// into function calls and operators.
engine.set_optimization_level(OptimizationLevel::Full);

// Create initialized scope
let mut scope = Scope::new();
scope.push_constant("x", 42_i64);   // 'x' is a constant

// Compile a script made up of script segments to an AST and store it for later evaluation.
// Notice that `Full` optimization is on, so constants are folded
// into function calls and operators.
let ast = engine.compile_scripts_with_scope(&mut scope, &[
            "if x > 40",            // all 'x' are replaced with 42
            "{ x } el",
            "se { 0 }"              // segments do not need to be valid scripts!
])?;

// Normally this would have failed because no scope is passed into the 'eval_ast'
// call and so the variable 'x' does not exist.  Here, it passes because the script
// has been optimized and all references to 'x' are already gone.
assert_eq!(engine.eval_ast::<i64>(&ast)?, 42);

pub fn compile_file(&self, path: PathBuf) -> Result<AST, Box<EvalAltResult>>

Compile a script file into an AST, which can be used later for evaluation.

Example

use rhai::Engine;

let engine = Engine::new();

// Compile a script file to an AST and store it for later evaluation.
// Notice that a PathBuf is required which can easily be constructed from a string.
let ast = engine.compile_file("script.rhai".into())?;

for _ in 0..42 {
    engine.eval_ast::<i64>(&ast)?;
}

pub fn compile_file_with_scope(
    &self,
    scope: &Scope,
    path: PathBuf
) -> Result<AST, Box<EvalAltResult>>

Compile a script file into an AST using own scope, which can be used later for evaluation.

The scope is useful for passing constants into the script for optimization when using OptimizationLevel::Full.

Example

use rhai::{Engine, Scope, OptimizationLevel};

let mut engine = Engine::new();

// Set optimization level to 'Full' so the Engine can fold constants.
engine.set_optimization_level(OptimizationLevel::Full);

// Create initialized scope
let mut scope = Scope::new();
scope.push_constant("x", 42_i64);   // 'x' is a constant

// Compile a script to an AST and store it for later evaluation.
// Notice that a PathBuf is required which can easily be constructed from a string.
let ast = engine.compile_file_with_scope(&mut scope, "script.rhai".into())?;

let result = engine.eval_ast::<i64>(&ast)?;

pub fn parse_json(
    &self,
    json: &str,
    has_null: bool
) -> Result<Map, Box<EvalAltResult>>

Parse a JSON string into a map.

Set has_null to true in order to map null values to (). Setting it to false will cause a variable not found error during parsing.

Example

use rhai::Engine;

let engine = Engine::new();

let map = engine.parse_json(r#"{"a":123, "b":42, "c":false, "d":null}"#, true)?;

assert_eq!(map.len(), 4);
assert_eq!(map.get("a").cloned().unwrap().cast::<i64>(), 123);
assert_eq!(map.get("b").cloned().unwrap().cast::<i64>(), 42);
assert_eq!(map.get("c").cloned().unwrap().cast::<bool>(), false);
assert_eq!(map.get("d").cloned().unwrap().cast::<()>(), ());

pub fn compile_expression(&self, script: &str) -> Result<AST, ParseError>

Example

use rhai::Engine;

let engine = Engine::new();

// Compile a script to an AST and store it for later evaluation
let ast = engine.compile_expression("40 + 2")?;

for _ in 0..42 {
    assert_eq!(engine.eval_ast::<i64>(&ast)?, 42);
}

pub fn compile_expression_with_scope(

// Set optimization level to 'Full' so the Engine can fold constants
// into function calls and operators.
engine.set_optimization_level(OptimizationLevel::Full);

// Create initialized scope
let mut scope = Scope::new();
scope.push_constant("x", 10_i64);   // 'x' is a constant

// Compile a script to an AST and store it for later evaluation.
// Notice that `Full` optimization is on, so constants are folded
// into function calls and operators.
let ast = engine.compile_expression_with_scope(&mut scope,
            "2 + (x + x) * 2"    // all 'x' are replaced with 10
)?;

// Normally this would have failed because no scope is passed into the 'eval_ast'
// call and so the variable 'x' does not exist.  Here, it passes because the script
// has been optimized and all references to 'x' are already gone.
assert_eq!(engine.eval_ast::<i64>(&ast)?, 42);

pub fn call_fn_dynamic(
    &self,
    scope: &mut Scope,
    ast: &AST,
    name: &str,
    arg_values: &mut [Dynamic]
) -> Result<Dynamic, Box<EvalAltResult>>

Call a script function defined in an AST with multiple Dynamic arguments.

WARNING

All the arguments are consumed, meaning that they're replaced by (). This is to avoid unnecessarily cloning the arguments. Do you use the arguments after this call. If you need them afterwards, clone them before calling this function.

Example

use rhai::{Engine, Scope};

let engine = Engine::new();

let ast = engine.compile(r"
    fn add(x, y) { len(x) + y + foo }
    fn add1(x)   { len(x) + 1 + foo }
    fn bar()     { foo/2 }

assert_eq!(result.cast::<i64>(), 21);

pub fn optimize_ast(
    &self,
    scope: &Scope,
    ast: AST,
    optimization_level: OptimizationLevel
) -> AST

Optimize the AST with constants defined in an external Scope. An optimized copy of the AST is returned while the original AST is consumed.

Although optimization is performed by default during compilation, sometimes it is necessary to re-optimize an AST. For example, when working with constants that are passed in via an external scope, it will be more efficient to optimize the AST once again to take advantage of the new constants.

With this method, it is no longer necessary to recompile a large script. The script AST can be compiled just once. Before evaluation, constants are passed into the Engine via an external scope (i.e. with scope.push_constant(...)). Then, the `AST is cloned and the copy re-optimized before running.

pub fn on_progress(
    &mut self,
    callback: impl Fn(u64) -> bool + SendSync + 'static
)

Register a callback for script evaluation progress.

Example

use rhai::Engine;

let result = Arc::new(RwLock::new(0_u64));
let logger = result.clone();

let mut engine = Engine::new();

engine.on_progress(move |ops| {
    if ops > 10000 {
        false
    } else if ops % 800 == 0 {
        *logger.write().unwrap() = ops;
        true
    } else {
        true
    }
});

engine.consume("for x in range(0, 50000) {}")
    .expect_err("should error");

assert_eq!(*result.read().unwrap(), 9600);

pub fn on_print(&mut self, callback: impl Fn(&str) + SendSync + 'static)

Override default action of print (print to stdout using println!)

Example

use rhai::Engine;

let result = Arc::new(RwLock::new(String::from("")));

let mut engine = Engine::new();

// Override action of 'print' function
let logger = result.clone();
engine.on_print(move |s| logger.write().unwrap().push_str(s));

engine.consume("print(40 + 2);")?;

assert_eq!(*result.read().unwrap(), "42");

pub fn on_debug(&mut self, callback: impl Fn(&str) + SendSync + 'static)

Override default action of debug (print to stdout using println!)

Example

use rhai::Engine;

let result = Arc::new(RwLock::new(String::from("")));

let mut engine = Engine::new();

// Override action of 'print' function
let logger = result.clone();
engine.on_debug(move |s| logger.write().unwrap().push_str(s));

engine.consume(r#"debug("hello");"#)?;

assert_eq!(*result.read().unwrap(), r#""hello""#);

impl Engine

pub fn new() -> Self
