Struct rsjsonnet_lang::program::Program

pub struct Program { /* private fields */ }

Jsonnet program state and evaluator.

See the module-level documentation for more information.

Implementations

impl Program

pub fn new() -> Self

Creates a new Program.

pub fn str_interner(&self) -> &StrInterner

pub fn span_manager(&self) -> &SpanManager

pub fn span_manager_mut(&mut self) -> &mut SpanManager

pub fn gc(&mut self)

Runs garbage collection unconditionally.

pub fn maybe_gc(&mut self)

Runs garbage collection under certain conditions.

pub fn set_max_stack(&mut self, max_stack: usize)

Sets the maximum call stack size.

The default is 500.

pub fn get_stdlib_source(&self) -> (SourceId, &[u8])

Returns the source of the part of the standard library that is implemented in Jsonnet.

pub fn add_ext_var(&mut self, name: InternedStr, thunk: &Thunk)

Adds an external variable.

External variables can be accessed within a Jsonnet program with the std.extVar function.

pub fn register_native_func( &mut self, name: InternedStr, params: &[InternedStr], )

Registers a native function.

Native functions can be accessed within a Jsonnet program with the std.native function.

The actual behavior of the native function should be implemented in Callbacks::native_call.

pub fn value_to_thunk(&mut self, value: &Value) -> Thunk

Creates a thunk with an already evaluated value.

pub fn make_array(&mut self, items: &[Value]) -> Value

Creates an array value.

pub fn make_object(&mut self, obj_fields: &[(InternedStr, Value)]) -> Value

Creates an object value.

pub fn load_source( &mut self, span_ctx: SpanContextId, input: &[u8], with_stdlib: bool, this_file: &str, ) -> Result<Thunk, LoadError>

Loads a Jsonnet source into a thunk.

with_stdlib specifies whether the standard library will be available as std. this_file will be the value of std.thisFile.

pub fn eval_value( &mut self, thunk: &Thunk, callbacks: &mut dyn Callbacks, ) -> Result<Value, EvalError>

Evaluates a thunk into a value.

pub fn eval_call( &mut self, func: &Thunk, pos_args: &[Thunk], named_args: &[(InternedStr, Thunk)], callbacks: &mut dyn Callbacks, ) -> Result<Value, EvalError>

Evaluates a function call.

pub fn manifest_json( &mut self, value: &Value, multiline: bool, ) -> Result<String, EvalError>

Manifests a value as JSON.

Trait Implementations

impl Default for Program

fn default() -> Self

Returns the “default value” for a type.
