Struct FuncType

pub struct FuncType { /* private fields */ }

A FuncType represents the parameter and result type(s) of a Wasm func.

Implementations

impl FuncType

pub fn new( params: impl Into<Vec<(String, Type)>>, results: impl Into<Vec<(String, Type)>>, ) -> Result<Self, WasmValueError>

Returns a new FuncType with the given param and result type(s). Returns an error if the resulting func type would be invalid in the component model, e.g. has any unnamed results with more than one result type.

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 Display for FuncType

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

Formats the value using the given formatter.

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.

impl WasmFunc for FuncType

type Type = Type

A type representing types of these params and results.

fn params(&self) -> Box<dyn Iterator<Item = Self::Type> + '_>

Returns an iterator of the func’s parameter types.

fn param_names(&self) -> Box<dyn Iterator<Item = Cow<'_, str>> + '_>

Returns an iterator of the func’s parameter names. Must be the same length as the iterator returned by params or empty if this WasmFunc impl does not support param names.

fn results(&self) -> Box<dyn Iterator<Item = Self::Type> + '_>

Returns an iterator of the func’s result types.

fn result_names(&self) -> Box<dyn Iterator<Item = Cow<'_, str>> + '_>

Returns an iterator of the func’s result names. Must be the same length as the iterator returned by results or empty if there are no named results or if this WasmFunc impl does not support result names.
