Struct FunctionContext

pub struct FunctionContext<'context> {
    pub name: Arc<String>,
    pub this: Option<Value>,
    pub ptx: &'context Context<'context>,
    pub args: Vec<Expression>,
    pub arg_idx: usize,
}

FunctionContext is a context object passed to functions when they are called.

It contains references to the target object (if the function is called as a method), the program context (Context) which gives functions access to variables, and the arguments to the function call.

Fields

name: Arc<String>

this: Option<Value>

ptx: &'context Context<'context>

args: Vec<Expression>

arg_idx: usize

Implementations

impl<'context> FunctionContext<'context>

pub fn new( name: Arc<String>, this: Option<Value>, ptx: &'context Context<'context>, args: Vec<Expression>, ) -> Self

pub fn resolve<R>(&self, resolver: R) -> Result<Value, ExecutionError>

where R: Resolver,

Resolves the given expression using the program’s Context.

pub fn error<M: ToString>(&self, message: M) -> ExecutionError

Returns an execution error for the currently execution function.

Trait Implementations

impl<'context> Clone for FunctionContext<'context>

fn clone(&self) -> FunctionContext<'context>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
