Struct flux_middle::rty::AliasTy

pub struct AliasTy {
    pub def_id: DefId,
    pub args: GenericArgs,
    pub refine_args: RefineArgs,
}

Fields

def_id: DefId

args: GenericArgs

refine_args: RefineArgs

Holds the refinement-arguments for opaque-types; empty for projections

Implementations

impl AliasTy

pub fn new(def_id: DefId, args: GenericArgs, refine_args: RefineArgs) -> Self

impl AliasTy

This methods work only with associated type projections (i.e., no opaque types)

pub fn self_ty(&self) -> SubsetTyCtor

pub fn with_self_ty(&self, self_ty: SubsetTyCtor) -> Self

Trait Implementations

impl Clone for AliasTy

fn clone(&self) -> AliasTy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AliasTy

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

Formats the value using the given formatter.

impl<__D: TyDecoder> Decodable<__D> for AliasTy

fn decode(__decoder: &mut __D) -> Self

impl<__E: TyEncoder> Encodable<__E> for AliasTy

fn encode(&self, __encoder: &mut __E)

impl Hash for AliasTy

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 PartialEq for AliasTy

fn eq(&self, other: &AliasTy) -> 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> ToRustc<'tcx> for AliasTy

type T = AliasTy<TyCtxt<'tcx>>

fn to_rustc(&self, tcx: TyCtxt<'tcx>) -> Self::T

impl TypeFoldable for AliasTy

fn try_fold_with<__F: FallibleTypeFolder>( &self, __folder: &mut __F, ) -> Result<Self, __F::Error>

fn fold_with<F: TypeFolder>(&self, folder: &mut F) -> Self

fn normalize_projections<'tcx>( &self, genv: GlobalEnv<'_, 'tcx>, infcx: &InferCtxt<'tcx>, callsite_def_id: DefId, ) -> QueryResult<Self>

fn normalize(&self, defns: &SpecFuncDefns) -> Self

Normalize expressions by applying beta reductions for tuples and lambda abstractions.

fn replace_holes( &self, f: impl FnMut(&[BoundVariableKinds], HoleKind) -> Expr, ) -> Self

Replaces all holes with the result of calling a closure. The closure takes a list with all the layers of bound variables at the point the hole was found. Each layer corresponds to the list of bound variables at that level. The list is ordered from outermost to innermost binder, i.e., the last element is the binder closest to the hole.

fn with_holes(&self) -> Self

Remove all refinements and turn each underlying BaseTy into a TyKind::Exists with a TyKind::Constr and a hole. For example, Vec<{v. i32[v] | v > 0}>[n] becomes {n. Vec<{v. i32[v] | *}>[n] | *}.

fn replace_evars(&self, evars: &EVarSol) -> Self

fn shift_in_escaping(&self, amount: u32) -> Self

fn shift_out_escaping(&self, amount: u32) -> Self

fn erase_regions(&self) -> Self

impl TypeVisitable for AliasTy

fn visit_with<__V: TypeVisitor>( &self, __visitor: &mut __V, ) -> ControlFlow<__V::BreakTy>

fn has_escaping_bvars(&self) -> bool

fn has_escaping_bvars_at_or_above(&self, binder: DebruijnIndex) -> bool

Returns true if self has any late-bound vars that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound vars that appear free.

fn fvars(&self) -> FxHashSet<Name>

Returns the set of all free variables. For example, Vec<i32[n]>{v : v > m} returns {n, m}.
