acid_io

A pared-down version of Rust's std::io usable in no_std contexts.


Rust's std::io provides common interfaces that are used widely in the Rust ecosystem for reading and writing data. However, as of 2022, these interfaces are not available in no_std builds.

This crate provides drop-in replacements for the types and traits exposed by std::io which can be used with no_std.

Example

#![no_std]

use acid_io::{
    byteorder::{BE, LE, ReadBytesExt, WriteBytesExt},
    Cursor, Read, Seek, SeekFrom, Write,
};

let mut buf = [0u8; 10];
let mut curs = Cursor::new(&mut buf);

curs.write_u8(1)?;
curs.write_u16::<BE>(2)?;
curs.write_u32::<LE>(3)?;

curs.seek(SeekFrom::Start(0))?;

assert_eq!(curs.read_u8()?, 1);
assert_eq!(curs.read_u16::<BE>()?, 2);
assert_eq!(curs.read_u32::<LE>()?, 3);

Feature flags

  • std

    Replaces all items with re-exports of their counterparts in std::io. This effectively makes acid_io an alias of std::io, but missing any items that acid_io wouldn't otherwise provide.

  • alloc

    Exposes BufReader and BufWriter, as well as those trait methods which take or return Vec or String.

  • byteorder

    Exposes acid_io::byteorder, which contains implementations of ReadBytesExt and WriteBytesExt for acid_io's Read and Write traits. Also re-exports the rest of byteorder.
