Expand description

Something that provides a strategy for passing a type between wasm and the host.

This trait exposes the same functionality as crate::host::IntoFFIValue and crate::host::FromFFIValue to delegate the implementation for a type to a different type.

This trait is used for the host implementation.

Required methods

Convert the given instance to the ffi value.

For more information see: crate::host::IntoFFIValue::into_ffi_value

Create T from the given ffi value.

For more information see: crate::host::FromFFIValue::from_ffi_value
