Crate rend[−][src]
Expand description
rend
rend is a library that provides endian-aware primitives for Rust.
It’s similar in design to simple_endian, but has
support for more builtin types such as atomics and nonzero integers. It also has support for
const functions since it does not rely on traits.
rend does not provide endian-aware types for types that are inherently endian-agnostic, such as
bool and u8. It does not provide endian-aware types for types that have an
architecture-dependent size, such as isize and usize. It’s also not extensible to custom
types.
rend is intended to be used to build portable types that can be shared between different architectures, especially with zero-copy deserialization.
Features
std: Enables standard library support (enabled by default)validation: Enables validation support throughbytecheck
Example:
use rend::*; let little_int = i32_le::new(0x12345678); // Internal representation is little-endian assert_eq!( [0x78, 0x56, 0x34, 0x12], unsafe { ::core::mem::transmute::<_, [u8; 4]>(little_int) } ); // Can also be made with `.into()` let little_int: i32_le = 0x12345678.into(); // Still formats correctly assert_eq!("305419896", format!("{}", little_int)); assert_eq!("0x12345678", format!("0x{:x}", little_int)); let big_int = i32_be::new(0x12345678); // Internal representation is big-endian assert_eq!( [0x12, 0x34, 0x56, 0x78], unsafe { ::core::mem::transmute::<_, [u8; 4]>(big_int) } ); // Can also be made with `.into()` let big_int: i32_be = 0x12345678.into(); // Still formats correctly assert_eq!("305419896", format!("{}", big_int)); assert_eq!("0x12345678", format!("0x{:x}", big_int));
