}
Expand description

Represents the repr options provided by the user,

Fields

int: Option<IntType>align: Option<Align>pack: Option<Align>flags: ReprFlags

Implementations

Returns the discriminant type, given these repr options. This must only be called on enums!

Returns true if this #[repr()] should inhabit “smart enum layout” optimizations, such as representing Foo<&T> as a single pointer.

Returns true if this #[repr()] should inhibit struct field reordering optimizations, such as with repr(C), repr(packed(1)), or repr(<int>).

Returns true if this #[repr()] should inhibit union ABI optimisations.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
