Expand description

Details of why a pointer had to be in-bounds.

Variants

`DerefTest`

We are dereferencing a pointer (i.e., creating a place).

`MemoryAccessTest`

We are access memory.

`PointerArithmeticTest`

We are doing pointer arithmetic.

`OffsetFromTest`

We are doing pointer offset_from.

`InboundsTest`

None of the above – generic/unspecific inbounds test.

Trait Implementations

source

impl Clone for CheckInAllocMsg

source

fn clone(&self) -> CheckInAllocMsg

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

impl Debug for CheckInAllocMsg

source

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

Formats the value using the given formatter. Read more

source

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

When this is printed as an error the context looks like this: “{msg}{pointer} is a dangling pointer”.

source

default fn fingerprint_style() -> FingerprintStyle

source

default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more

source

default fn to_debug_str(&self, Ctxt) -> String

source

default fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it. Read more
