Expand description
A trait to convert a Rust value to a WasmNativeType
value,
or to convert WasmNativeType
value to a Rust value.
This trait should ideally be split into two traits:
FromNativeWasmType
and ToNativeWasmType
but it creates a
non-negligible complexity in the WasmTypeList
implementation.
Safety
This trait is unsafe given the nature of how values are written and read from the native stack
Required Associated Types§
sourcetype Native: NativeWasmTypeInto
type Native: NativeWasmTypeInto
Native Wasm type.
Required Methods§
sourcefn from_native(native: Self::Native) -> Self
fn from_native(native: Self::Native) -> Self
Convert a value of kind Self::Native
to Self
.
Panics
This method panics if native
cannot fit in the Self
type`.
Provided Methods§
sourcefn is_from_store(&self, _store: &impl AsStoreRef) -> bool
fn is_from_store(&self, _store: &impl AsStoreRef) -> bool
Returns whether the given value is from the given store.
This always returns true for primitive types that can be used with any context.
