}Expand description
The WasmTypeList trait represents a tuple (list) of Wasm
typed values. It is used to get low-level representation of
such a tuple.
Required Associated Types§
Required Methods§
sourceunsafe fn from_array(store: &mut impl AsStoreMut, array: Self::Array) -> Self
unsafe fn from_array(store: &mut impl AsStoreMut, array: Self::Array) -> Self
Constructs Self based on an array of values.
Safety
sourceunsafe fn from_slice(
store: &mut impl AsStoreMut,
slice: &[RawValue]
) -> Result<Self, TryFromSliceError>
unsafe fn from_slice( store: &mut impl AsStoreMut, slice: &[RawValue] ) -> Result<Self, TryFromSliceError>
Constructs Self based on a slice of values.
from_slice returns a Result because it is possible
that the slice doesn’t have the same size than
Self::Array, in which circumstance an error of kind
TryFromSliceError will be returned.
Safety
sourceunsafe fn into_array(self, store: &mut impl AsStoreMut) -> Self::Array
unsafe fn into_array(self, store: &mut impl AsStoreMut) -> Self::Array
Builds and returns an array of type Array from a tuple
(list) of values.
Safety
sourcefn empty_array() -> Self::Array
fn empty_array() -> Self::Array
Allocates and return an empty array of type Array that
will hold a tuple (list) of values, usually to hold the
returned values of a WebAssembly function call.
sourceunsafe fn from_c_struct(
store: &mut impl AsStoreMut,
c_struct: Self::CStruct
) -> Self
unsafe fn from_c_struct( store: &mut impl AsStoreMut, c_struct: Self::CStruct ) -> Self
Builds a tuple (list) of values from a C struct of type
CStruct.
Safety
sourceunsafe fn into_c_struct(self, store: &mut impl AsStoreMut) -> Self::CStruct
unsafe fn into_c_struct(self, store: &mut impl AsStoreMut) -> Self::CStruct
Builds and returns a C struct of type CStruct from a
tuple (list) of values.
Safety
sourceunsafe fn write_c_struct_to_ptr(c_struct: Self::CStruct, ptr: *mut RawValue)
unsafe fn write_c_struct_to_ptr(c_struct: Self::CStruct, ptr: *mut RawValue)
Writes the contents of a C struct to an array of RawValue.
Safety
sourcefn wasm_types() -> &'static [Type]
fn wasm_types() -> &'static [Type]
Get the Wasm types for the tuple (list) of currently represented values.
