Struct wasmedge_sdk::FuncType

pub struct FuncType { /* private fields */ }

Parses in-memory bytes as either the WebAssembly Text format, or a binary WebAssembly module Struct of WasmEdge FuncType.

A FuncType is used to declare the types of the parameters and return values of a WasmEdge Func to be created.

Implementations

impl FuncType

pub fn new(
    args: Option<Vec<ValType, Global>>,
    returns: Option<Vec<ValType, Global>>
) -> FuncType

Creates a new FuncType with the given types of arguments and returns.

Arguments

• args - A vector of ValTypes that represent the types of the arguments.

• returns - A vector of ValTypes that represent the types of the returns.

pub fn args(&self) -> Option<&[ValType]>

Returns the types of the arguments of a host function.

pub fn args_len(&self) -> u32

Returns the number of the arguments of a host function.

pub fn returns(&self) -> Option<&[ValType]>

Returns the types of the returns of a host function.

pub fn returns_len(&self) -> u32

Returns the number of the returns of a host 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<(), Error>

Formats the value using the given formatter.

impl Default for FuncType

fn default() -> FuncType

Returns the “default value” for a type.

impl From<FuncType> for FuncType

fn from(ty: FuncType) -> FuncType

Converts to this type from the input type.

impl PartialEq<FuncType> 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.
