[−][src]Trait web_glitz::pipeline::interface_block::StableRepr

pub unsafe trait StableRepr { }

Marker trait for types that are guaranteed have a stable memory representation across builds.

This trait may be unsafely implemented on types to mark them as having a stable representation.

use web_glitz::pipeline::interface_block::StableRepr;

#[repr(C, align(16))]
struct MyType {
    member: f32
}

unsafe impl StableRepr for MyType {}

This trait is required to be implemented for any type that wishes to implement InterfaceBlock or InterfaceBlockComponent.

This trait is already implemented for any type marked with std140::ReprStd140, including any user-defined structs marked with the #[std140::repr_std140] attribute.

Unsafe

This trait should only be implemented on types which have a representation that is guaranteed to be stable across builds. By default, the Rust compiler gives no guarantees on the memory layout of non-primitive types such as (user-defined) structs or tuples, which allows the compiler to optimize their memory layout. However, the compiler may be instructed to use a well-defined memory layout with the #[repr] attribute, e.g. #[repr(C)].
