Struct parity_wasm::elements::FunctionType

pub struct FunctionType { /* fields omitted */ }

Function signature type.

Methods

impl FunctionType

pub fn new(params: Vec<ValueType>, return_type: Option<ValueType>) -> Self

New function type given the signature in-params(params) and return type (return_type)

pub fn form(&self) -> u8

Function form (currently only valid value is 0x60)

Important traits for &'_ [u8]

impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]

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

Parameters in the function signature.

Important traits for Vec<u8>

impl Write for Vec<u8>

pub fn params_mut(&mut self) -> &mut Vec<ValueType>

Mutable parameters in the function signature.

pub fn return_type(&self) -> Option<ValueType>

Return type in the function signature, if any.

pub fn return_type_mut(&mut self) -> &mut Option<ValueType>

Mutable type in the function signature, if any.

Trait Implementations

impl Eq for FunctionType

impl Default for FunctionType

fn default() -> Self

Returns the "default value" for a type.

impl PartialEq<FunctionType> for FunctionType

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Clone for FunctionType

fn clone(&self) -> FunctionType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionType

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

Formats the value using the given formatter.

impl Hash for FunctionType

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, 

Feeds a slice of this type into the given [Hasher].
