Struct DynFunc 

pub struct DynFunc<'a> { /* private fields */ }

A representation of an exported WebAssembly function.

Implementations

impl<'a> DynFunc<'a>

pub fn call(&self, params: &[Value]) -> CallResult<Vec<Value>>

Call an exported WebAssembly function safely.

Pass arguments by wrapping each one in the Value enum. The returned values are also each wrapped in a Value.

Note:

This returns CallResult<Vec<Value>> in order to support the future multi-value returns WebAssembly feature.

Usage:

instance
    .dyn_func("foo")?
    .call(&[])?;

pub fn signature(&self) -> &FuncSig

Gets the signature of this Dynfunc.

pub fn raw(&self) -> *const Func

Gets a const pointer to the function represent by this DynFunc.

Trait Implementations

impl<'a> Exportable<'a> for DynFunc<'a>

fn get_self(exports: &'a Exports, name: &str) -> ResolveResult<Self>

Implementation of how to get the export corresponding to the implementing type from an [Instance] by name.

impl<'a> From<DynFunc<'a>> for Anyfunc<'a>

fn from(function: DynFunc<'a>) -> Self

Converts to this type from the input type.

impl<'a> TryFrom<Anyfunc<'a>> for DynFunc<'a>

type Error = ()

The type returned in the event of a conversion error.

fn try_from(anyfunc: Anyfunc<'a>) -> Result<Self, Self::Error>

Performs the conversion.
