Struct Std140CompatTypeInfo 

pub struct Std140CompatTypeInfo {
    type_id: Word,
    member_indices: Vec<u32>,
}

Information about a type for which we have declared a std140 layout compatible variant, because the type is used in a uniform but does not adhere to std140 requirements. The uniform will be declared using the type type_id, and the result of any Load will be immediately converted to the base type. This is used for matrices with 2 rows, as well as any arrays or structs containing such matrices.

Fields

type_id: Word

ID of the std140 compatible type declaration.

member_indices: Vec<u32>

For structs, a mapping of Naga IR struct member indices to the indices used in the generated SPIR-V. For non-struct types this will be empty.
