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
