Trait sp_wasm_interface::Function

    // Required methods
    fn name(&self) -> &str;
    fn signature(&self) -> Signature;
    fn execute(

}

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<dyn Function + 'static> for dyn Function

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

This method tests for self and other values to be equal, and is used by ==.

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

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