embedded-io-extras

embedded-io-extras is a no_std compatible library providing additional utilities, including a Cursor type. It functions like std::io::Cursor but is tailored for environments without standard libraries. This crate complements embedded-io.

Usage

Add this to your Cargo.toml:

[dependencies]
embedded-io-extras = "0.0.2"

and for no_std environments:

[dependencies]
embedded-io-extras = { version = "0.0.2", default-features = false, features = ["alloc"] }

• std: Enable this feature to use std with embedded-io. Enabled by default.
• alloc: Enable this feature to support dynamic memory allocation with embedded-io. Enabled by default.

Examples

use embedded_io_extras::{Cursor, Write};

fn main() {
    let mut cur = Cursor::new(Vec::new());
    assert_eq!(cur.write(&[1, 2, 3]).unwrap(), 3);
    assert_eq!(cur.position(), 3);
    assert_eq!(cur.get_ref(), &vec![1, 2, 3]);
}
