Overview

ezio - a crate for easy IO

ezio offers an easy to use IO API for reading and writing to files and stdio. ezio includes utilities for generating random numbers and other IO-like functionality. Performance and idiomatic error handling are explicit non-goals, so ezio is probably not suitable for production use. It is better suited for education, experimentation, and prototyping.

ezio wraps the standard library's IO APIs and other well-established crates, and is designed to interoperate with them, so ezio should be compatible with most upstream libraries.

Examples

use ezio::prelude::*;

fn main() {
    // Read a line from stdin
    let _ = stdio::read_line();

    // Iterate lines in a file
    for line in file::reader("path/to/file.txt") {
        // ...
    }

    // Read a whole file
    let _ = file::read("path/to/file.txt");

    // Write to a file
    file::write("path/to/file.txt", "Some text");

    // Write multiple things to a file
    let mut w = file::writer("path/to/file.txt");
    w.write("Some text\n");
    w.write("Some more text");

    // Generates a random u32
    let _ = random::u32();
}

Design principals

(ezio is work in progress, so these may still be aspirational)

  • Easy to use!
  • Easy to import - provide a prelude and most users will not need anything else
  • Simple module hierarchy
  • String-based, not byte-based by default
  • Panic-happy: panic by default, try_ versions of functions where you really need an error
  • Allocation-happy: returns Strings, etc rather than taking buffers
  • Compatible and interoperable with std IO so programs can gradually migrate from ezio to std::io
  • Just because we're doing unsophisticated IO, doesn't mean the rest of the program is unsophisticated. Therefore:
    • should be idiomatic Rust
    • should support generics and trait objects, etc

  • Implement a scan macro

    Implement a scan macro

    Should be easier to implement in ezio than in the general case because we don't need to worry about error handling or optimal performance. Something like the following should work:

    // Types should not always be required.
let (foo, bar): (u8, f64) = scanln!("{}, {}");

    alternative syntaxes:

    let foo: u8;
let bar: f64;
scanln!("{}, {}", foo, bar);

    let (foo, bar) = scanln!("{}, {}", u8, f64);

    There are many, many ways this could be enhanced following format strings.

  • Reference impls

    Reference impls

    Add implementations of Read for &Reader, etc., following File in std. This is not straightforward because the std trait functions require &mut self, so we either need to keep references to the sys impls (which take &self), if that is possible, or use a RefCell (though I think that would not support simultaneous reads) or some other hack.

    Stdio impls and Read for strings should be much easier.
