Expand description

Fast binary serialization and deserialization for types with a known maximum size.

Traits§

Peek: A trait for values that provide deserialization from buffers of bytes.
Poke: A trait for values that provide serialization into buffers of bytes.

ensure_red_zone: Add T::max_size() “red zone” (padding of zeroes) to the end of the vec of bytes. This allows deserialization to assert that at least T::max_size() bytes exist at all times.
peek_from_default^⚠: Peek helper for constructing a T by Default initialized stack allocation.
peek_from_slice: Peek inplace a T from a slice of bytes, returning a slice of the remaining bytes. src must contain at least T::max_size() bytes.
peek_from_uninit^⚠: Peek helper for constructing a T by Copying into an uninitialized stack allocation.
poke_extend_vec
poke_inplace_slice: Poke helper to insert a serialized version of src at the beginning for dst.
poke_into_vec: Poke helper to append a serialized version of src to the end of dst.
strip_red_zone: Remove the “red zone” (padding of zeroes) from the end of the vec of bytes. This is effectively the inverse of ensure_red_zone, with the caveat that space reserved for the red zone is not un-reserved. Callers are repsonsible for making sure the vec actually has a red zone, otherwise data bytes can get stripped instead.
