Struct rustc_middle::ty::ReprOptions

pub struct ReprOptions {
    pub int: Option<IntType>,
    pub align: Option<Align>,
    pub pack: Option<Align>,
    pub flags: ReprFlags,
}

Represents the repr options provided by the user,

Fields

int: Option<IntType>

align: Option<Align>

pack: Option<Align>

flags: ReprFlags

Implementations

impl ReprOptions

pub fn new(tcx: TyCtxt<'_>, did: DefId) -> ReprOptions

pub fn simd(&self) -> bool

pub fn c(&self) -> bool

pub fn packed(&self) -> bool

pub fn transparent(&self) -> bool

pub fn linear(&self) -> bool

pub fn hide_niche(&self) -> bool

pub fn discr_type(&self) -> IntType

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

pub fn inhibit_enum_layout_opt(&self) -> bool

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

pub fn inhibit_struct_field_reordering_opt(&self) -> bool

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

pub fn inhibit_union_abi_opt(&self) -> bool

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

Trait Implementations
