Crate file [−] [src]

File I/O 1-liners

file::get() and file::put() — read and write Vec<u8> with one function call.

extern crate file;

fn example() -> file::Result<()> {
    let data = file::get("some_input_file.dat")?;
    file::put("a.out", &data)?;
    Ok(())
}

file::Result is an alias for std::io::Result. You can use Result<(), Box<std::error::Error>> in places where you don't want to expose the error type.

Text file 1-liners

file::get_text() and file::put_text() — read and write String with one function call.

extern crate file;

fn example() -> file::Result<()> {
    let string = file::get_text("hello.txt")?;
    file::put("bye.txt", &string)?;
    Ok(())
}

Functions

get	Read a file into `Vec<u8>` from the given path. The path can be a string or a `Path`.
get_text	Read an UTF-8 encoded file into `String` from the given path. The path can be a string or a `Path`.
put	Creates a file at the given path with contents of `Vec<u8>` or `&[u8]`, etc. Overwrites, non-atomically, if the file exists. The path can be a string or a `Path`.
put_text	Creates a file at the given path with given text contents, encoded as UTF-8. Overwrites, non-atomically, if the file exists. The path can be a string or a `Path`.
