Struct AlignAs

#[repr(C)]
pub struct AlignAs<B: ?Sized, T> {
    pub _align: [T; 0],
    pub bytes: B,
}

A hack to align a smaller type B with a bigger type T.

The usual use of this is with B = [u8] and T = u32. That is, it permits aligning a sequence of bytes on a 4-byte boundary. This is useful in contexts where one wants to embed a serialized dense DFA into a Rust a program while guaranteeing the alignment required for the DFA.

See dense::DFA::from_bytes for an example of how to use this type.

Fields

_align: [T; 0]

A zero-sized field indicating the alignment we want.

bytes: B

A possibly non-sized field containing a sequence of bytes.

Trait Implementations

impl<B: Debug + ?Sized, T: Debug> Debug for AlignAs<B, T>

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

Formats the value using the given formatter.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
