Enum rustc_middle::mir::interpret::allocation::AllocError
source · pub enum AllocError {
ScalarSizeMismatch(ScalarSizeMismatch),
ReadPointerAsInt(Option<BadBytesAccess>),
OverwritePartialPointer(Size),
ReadPartialPointer(Size),
InvalidUninitBytes(Option<BadBytesAccess>),
}
Expand description
We have our own error type that does not know about the AllocId
; that information
is added when converting to InterpError
.
Variants§
ScalarSizeMismatch(ScalarSizeMismatch)
A scalar had the wrong size.
ReadPointerAsInt(Option<BadBytesAccess>)
Encountered a pointer where we needed raw bytes.
OverwritePartialPointer(Size)
Partially overwriting a pointer.
ReadPartialPointer(Size)
Partially copying a pointer.
InvalidUninitBytes(Option<BadBytesAccess>)
Using uninitialized data where it is not allowed.

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.
