Enum rustc_middle::mir::interpret::AllocError

pub enum AllocError {
    ScalarSizeMismatch(ScalarSizeMismatch),
    ReadPointerAsInt(Option<BadBytesAccess>),
    OverwritePartialPointer(Size),
    ReadPartialPointer(Size),
    InvalidUninitBytes(Option<BadBytesAccess>),
}

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.

Implementations

impl AllocError

pub fn to_interp_error<'tcx>(self, alloc_id: AllocId) -> InterpError<'tcx>

Trait Implementations

impl Debug for AllocError

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

Formats the value using the given formatter.

impl From<ScalarSizeMismatch> for AllocError

fn from(s: ScalarSizeMismatch) -> Self

Converts to this type from the input type.

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.

Size: 48 bytes

Size for each variant:

• ScalarSizeMismatch: 16 bytes
• ReadPointerAsInt: 40 bytes
• OverwritePartialPointer: 8 bytes
• ReadPartialPointer: 8 bytes
• InvalidUninitBytes: 40 bytes
