Enum bytemuck::PodCastError

pub enum PodCastError {
    TargetAlignmentGreaterAndInputNotAligned,
    OutputSliceWouldHaveSlop,
    SizeMismatch,
    AlignmentMismatch,
}

The things that can go wrong when casting between Pod data forms.

Variants

TargetAlignmentGreaterAndInputNotAligned

You tried to cast a slice to an element type with a higher alignment requirement but the slice wasn’t aligned.

OutputSliceWouldHaveSlop

If the element size changes then the output slice changes length accordingly. If the output slice wouldn’t be a whole number of elements then the conversion fails.

SizeMismatch

When casting a slice you can’t convert between ZST elements and non-ZST elements. When casting an individual T, &T, or &mut T value the source size and destination size must be an exact match.

AlignmentMismatch

For this type of cast the alignments must be exactly the same and they were not so now you’re sad.

This error is generated only by operations that cast allocated types (such as Box and Vec), because in that case the alignment must stay exact.
