Struct FuncType

pub struct FuncType { /* private fields */ }

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: Vec<ValType>, returns: Vec<ValType>) -> 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) -> &[ValType]

Returns the types of the arguments of a host function.

pub fn args_len(&self) -> usize

Returns the number of the arguments of a host function.

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

Returns the types of the returns of a host function.

pub fn returns_len(&self) -> usize

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<&FuncTypeOwn> for FuncType

fn from(ty: &FuncTypeOwn) -> FuncType

Converts to this type from the input type.

impl PartialEq for FuncType

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

Tests for self and other values to be equal, and is used by ==.

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

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