Struct wasmer_runtime::DynFunc

pub struct DynFunc { /* fields omitted */ }

Represents a type-erased function provided by either the host or the WebAssembly program.

Implementations

impl DynamicFunc

pub fn new<F>(signature: &FunctionType, func: F) -> DynamicFunc where
    F: Fn(&mut Ctx, &[Value<Function>]) -> Result<Vec<Value<Function>>, RuntimeError> + 'static, 

Create a new DynamicFunc.

pub fn signature(&self) -> &FunctionType

Returns the full function signature.

pub fn params(&self) -> &[Type]

Returns the types of the function inputs.

pub fn returns(&self) -> &[Type]

Returns the types of the function outputs.

pub fn call(
    &self,
    params: &[Value<Function>]
) -> Result<Box<[Value<Function>]>, RuntimeError>

Call the function. In this case, it's an alias to dyn_call.

pub fn dyn_call(
    &self,
    params: &[Value<Function>]
) -> Result<Box<[Value<Function>]>, RuntimeError>

Call the function.

Trait Implementations

impl Clone for DynamicFunc

fn clone(&self) -> DynamicFunc

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Exportable<'a> for DynamicFunc

fn to_export(&self) -> Export

This function is used when providedd the [Extern] as exportable, so it can be used while instantiating the [Module].

fn get_self_from_extern(
    r#extern: &'a Extern
) -> Result<&'a DynamicFunc, ExportError>

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

impl<'_> From<&'_ Function> for DynamicFunc

fn from(new_function: &Function) -> DynamicFunc

Performs the conversion.

impl From<DynamicFunc> for Extern

fn from(dynamic_func: DynamicFunc) -> Extern

Performs the conversion.
