Crate zerocopy

Utilities for safe zero-copy parsing and serialization.

This crate provides utilities which make it easy to perform zero-copy parsing and serialization by allowing zero-copy conversion to/from byte slices.

This is enabled by three core marker traits:

• FromBytes indicates that a type may safely be converted from an arbitrary byte sequence
• AsBytes indicates that a type may safely be converted to a byte sequence
• Unaligned indicates that a type’s alignment requirement is 1

Types which implement a subset of these traits can then be converted to/from byte sequences with little to no runtime overhead.

Structs

LayoutVerified

A length- and alignment-checked reference to a byte slice which can safely be reinterpreted as another type.

Traits

AsBytes

Types which are safe to treat as an immutable byte slice.

ByteSlice

A mutable or immutable reference to a byte slice.

ByteSliceMut

A mutable reference to a byte slice.

FromBytes

Types for which any byte pattern is valid.

Unaligned

Types with no alignment requirement.
