Enum rustc_const_eval::interpret::AllocError

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.

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.
