Trait wasmtime::component::Lower

source ·
pub unsafe trait Lower: ComponentType { }
Expand description

Host types which can be passed to WebAssembly components.

This trait is implemented for all types that can be passed to components either as parameters of component exports or returns of component imports. This trait represents the ability to convert from the native host representation to the canonical ABI.

Built-in types to Rust such as Option<T> implement this trait as appropriate. For a mapping of component model to Rust types see ComponentType.

For user-defined types, for example record types mapped to Rust structs, this crate additionally has #[derive(Lower)].

Note that like ComponentType the definition of this trait is intended to be an internal implementation detail of Wasmtime at this time. It’s recommended to use the #[derive(Lower)] implementation instead.

Object Safety§

This trait is not object safe.
