Trait RefIntoWasmAbi 

pub trait RefIntoWasmAbi: Sealed {
    type Abi: WasmAbi;

    // Required methods
    fn describe_ref();
    fn ref_into_abi(&self) -> Self::Abi;
}

A type whose shared references can cross the Wasm ABI, i.e. for<'a> &'a Self: IntoWasmAbi.

Rust does not imply a trait’s where clauses on Self the way it implies supertraits, so an alias trait for that higher-ranked bound would not let generic code use &T: IntoWasmAbi. This trait carries the conversion itself instead, and experimental_generic_mono imports marshal a &T argument through it, so T: RefIntoWasmAbi is the bound they declare. It is sealed, holding exactly where the higher-ranked bound does.

⚠️ Unstable

This is part of the internal convert module, no stability guarantees are provided. Use at your own risk. See its documentation for more details.

Required Associated Types

type Abi: WasmAbi

The Wasm ABI type that &Self converts into.

Required Methods

fn describe_ref()

Describe &Self.

fn ref_into_abi(&self) -> Self::Abi

Convert &self into Self::Abi.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
