Enum rustc_mir_transform::ref_prop::Value

enum Value<'tcx> {
    Unknown,
    Pointer(Place<'tcx>, bool),
}

Variants

Unknown

Not a pointer, or we can’t know.

Pointer(Place<'tcx>, bool)

We know the value to be a pointer to this place. The boolean indicates whether the reference is mutable, subject the uniqueness rule.

Trait Implementations

impl<'tcx> Clone for Value<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for Value<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> PartialEq for Value<'tcx>

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<'tcx> Copy for Value<'tcx>

impl<'tcx> Eq for Value<'tcx>

impl<'tcx> StructuralPartialEq for Value<'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.
