Variants

ErrorGuaranteed

CastToBool

CastToChar

DifferingKinds

SizedUnsizedCast

Cast of thin to fat raw ptr (e.g., *const () as *const [u8]).

IllegalCast

NeedDeref

NeedViaPtr

NeedViaThinPtr

NeedViaInt

NonScalar

UnknownExprPtrKind

UnknownCastPtrKind

IntToFatCast(Option<&'static str>)

Cast of int to (possibly) fat raw pointer.

Argument is the specific name of the metadata in plain words, such as “a vtable” or “a length”. If this argument is None, then the metadata is unknown, for example, when we’re typechecking a type parameter with a ?Sized bound.

ForeignNonExhaustiveAdt

Trait Implementations

impl Clone for CastError

fn clone(&self) -> CastError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<ErrorGuaranteed> for CastError

fn from(_: ErrorGuaranteed) -> Self

Converts to this type from the input type.

impl Copy for CastError

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.
