Struct wasmtime_environ::wasmparser::FuncType

pub struct FuncType { /* private fields */ }

Represents a type of a function in a WebAssembly module.

Implementations

impl FuncType

pub fn new<P, R>(params: P, results: R) -> FuncType

where P: IntoIterator<Item = ValType>, R: IntoIterator<Item = ValType>,

Creates a new FuncType from the given params and results.

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

Returns a shared slice to the parameter types of the FuncType.

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

Returns a shared slice to the result types of the FuncType.

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<'a> FromReader<'a> for FuncType

fn from_reader( reader: &mut BinaryReader<'a>, ) -> Result<FuncType, BinaryReaderError>

Attempts to read Self from the provided binary reader, returning an error if it is unable to do so.

impl Hash for FuncType

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

where __H: Hasher,

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.

impl TryFrom<FuncType> for WasmFuncType

type Error = WasmError

The type returned in the event of a conversion error.

fn try_from( ty: FuncType, ) -> Result<WasmFuncType, <WasmFuncType as TryFrom<FuncType>>::Error>

Performs the conversion.

impl WasmFuncType for FuncType

fn len_inputs(&self) -> usize

Returns the number of input types.

fn len_outputs(&self) -> usize

Returns the number of output types.

fn input_at(&self, at: u32) -> Option<ValType>

Returns the type at given index if any.

fn output_at(&self, at: u32) -> Option<ValType>

Returns the type at given index if any.

fn inputs(&self) -> WasmFuncTypeInputs<'_, Self>

where Self: Sized,

Returns the list of inputs as an iterator.

fn outputs(&self) -> WasmFuncTypeOutputs<'_, Self>

where Self: Sized,

Returns the list of outputs as an iterator.
