Trait abi_stable::StableAbi

pub unsafe trait StableAbi: GetStaticEquivalent_ {
    type IsNonZeroType: Boolean;

    pub const LAYOUT: &'static TypeLayout;
    pub const ABI_CONSTS: AbiConsts;
}

Represents a type whose layout is stable.

This trait can be derived using #[derive(StableAbi)].

Safety

The layout specified in LAYOUT must be correct, otherwise type checking when loading a dynamic library would be unsound, and passing this into a dynamic library would be equivalent to transmuting it.

Caveats

This trait cannot be directly implemented for functions that take lifetime parameters, because of that,#[derive(StableAbi)] detects the presence of extern fn types in type definitions.

Associated Types

type IsNonZeroType: Boolean

Whether this type has a single invalid bit-pattern.

Possible values:True/False

Some standard library types have a single value that is invalid for them eg:0,null. these types are the only ones which can be stored in a Option<_> that implements StableAbi.

An alternative for types where IsNonZeroType=False,you can use ROption.

Non-exhaustive list of std types that are NonZero:

• &T (any T).

• &mut T (any T).

• extern "C" fn().

• std::ptr::NonNull

• std::num::NonZero*
