Struct LitToConstInput

pub struct LitToConstInput<'tcx> {
    pub lit: &'tcx LitKind,
    pub ty: Ty<'tcx>,
    pub neg: bool,
}

Input argument for tcx.lit_to_const.

Fields

lit: &'tcx LitKind

The absolute value of the resultant constant.

ty: Ty<'tcx>

The type of the constant.

neg: bool

If the constant is negative.

Trait Implementations

impl<'tcx> Clone for LitToConstInput<'tcx>

fn clone(&self) -> LitToConstInput<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for LitToConstInput<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx> EraseType for LitToConstInput<'tcx>

type Result = [u8; 24]

impl<'tcx> Hash for LitToConstInput<'tcx>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for LitToConstInput<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher, )

impl<'tcx> Key for LitToConstInput<'tcx>

type Cache<V> = DefaultCache<LitToConstInput<'tcx>, V>

fn default_span(&self, _tcx: TyCtxt<'_>) -> Span

In the event that a cycle occurs, if no explicit span has been given for a query with key self, what span should we use?

fn key_as_def_id(&self) -> Option<DefId>

If the key is a DefId or DefId–equivalent, return that DefId. Otherwise, return None.

fn def_id_for_ty_in_cycle(&self) -> Option<DefId>

Used to detect when ADT def ids are used as keys in a cycle for better error reporting.

impl<'tcx> PartialEq for LitToConstInput<'tcx>

fn eq(&self, other: &LitToConstInput<'tcx>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'tcx> Copy for LitToConstInput<'tcx>

impl<'tcx> Eq for LitToConstInput<'tcx>

impl<'tcx> StructuralPartialEq for LitToConstInput<'tcx>

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.
