Enum rustc_middle::mir::interpret::allocation::AllocError

source ·

pub enum AllocError {
    ScalarSizeMismatch(ScalarSizeMismatch),

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.

`ReadPointerAsBytes`

Encountered a pointer where we needed raw bytes.

`PartialPointerOverwrite(Size)`

Partially overwriting a pointer.

`PartialPointerCopy(Size)`

Partially copying a pointer.

`InvalidUninitBytes(Option<UninitBytesAccess>)`

Using uninitialized data where it is not allowed.
