no-std-io
Fork
no-std-io2 is a fork of no-std-io, which is a fork of core2.
Overview
Ever wanted a Cursor or the Error trait in no_std? Well now you can have it. A 'fork' of Rust's std modules for no_std environments, with the added benefit of optionally taking advantage of alloc.
The goal of this crate is to provide a stable interface for building I/O and error trait functionality in
no_std environments. The current code corresponds to the most recent stable API of Rust 1.56.0.
It is also a goal to achieve a true alloc-less experience, with opt-in alloc support.
This crate works on stable with some limitations in functionality, and nightly without limitations by adding
the relevant feature flag.
This crate is std by default -- use no default features to get no_std mode.
Usage
[dependencies]
no_std_io2 = "0.8"
Add the crate, use the things you would usually want from std::io, but instead from no_std_io2::io, and
use no_std_io2::error::Error in place of std::error::Error.
Features
- std: enables
stdpass-throughs for the polyfilled types, but allows accessing the new types - alloc: enable aspects of the
ReadandWritetraits that requireallocsupport (WIP) - nightly: enables nightly-only features.
Differences to std::io
- No
std::io::Error, so we have our own copy without anyOserror functions IoSliceand the*_vectoredfamily of functions are not implemented.BufReaderandBufWriterhave a different signature, as they now use a const generic bounded array for the internal buffer.
Other than items perhaps being entirely missing or certain functions unavailable on some traits, no function signatures have been changed.
Limitations
Errortrait is not implemented for!becausenever_typefeature is not yet stabilized.
