Struct FunctionContext

Source
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,
}
Expand description

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.
