Trait Function 

pub trait Function:
    MaybeRefUnwindSafe
    + Send
    + Sync {
    // Required methods
    fn name(&self) -> &str;
    fn signature(&self) -> Signature;
    fn execute(
        &self,
        context: &mut dyn FunctionContext,
        args: &mut dyn Iterator<Item = Value>,
    ) -> Result<Option<Value>>;
}

Something that provides a function implementation on the host for a wasm function.

Required Methods

fn name(&self) -> &str

Returns the name of this function.

fn signature(&self) -> Signature

Returns the signature of this function.

fn execute( &self, context: &mut dyn FunctionContext, args: &mut dyn Iterator<Item = Value>, ) -> Result<Option<Value>>

Execute this function with the given arguments.

Trait Implementations

impl PartialEq for dyn Function

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
