Trait wasmer::FromToNativeWasmType
source · [−]pub unsafe trait FromToNativeWasmType where
Self: Sized, {
type Native: NativeWasmTypeInto;

}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
Native Wasm type.
Required Methods
fn 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
fn 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.
