Struct wasmtime::FuncType

pub struct FuncType { /* private fields */ }

A descriptor for a function in a WebAssembly module.

WebAssembly functions can have 0 or more parameters and results.

Implementations

impl FuncType

pub fn new( params: impl IntoIterator<Item = ValType>, results: impl IntoIterator<Item = ValType>, ) -> FuncType

Creates a new function descriptor from the given parameters and results.

The function descriptor returned will represent a function which takes params as arguments and returns results when it is finished.

pub fn params(&self) -> impl ExactSizeIterator<Item = ValType> + '_

Returns the list of parameter types for this function.

pub fn results(&self) -> impl ExactSizeIterator<Item = ValType> + '_

Returns the list of result types for this function.

Trait Implementations

impl Clone for FuncType

fn clone(&self) -> FuncType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FuncType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<FuncType> for ExternType

fn from(ty: FuncType) -> ExternType

Converts to this type from the input type.

impl Hash for FuncType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FuncType

fn eq(&self, other: &FuncType) -> 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.
