Trait artichoke::prelude::Io

pub trait Io {
    type Error;
    fn print<T>(&mut self, message: T) -> Result<(), Self::Error>
    where
        T: AsRef<[u8]>;

    fn puts<T>(&mut self, message: T) -> Result<(), Self::Error>
    where
        T: AsRef<[u8]>,
    { ... }
}

Make I/O external to the interpreter.

Associated Types

type Error

Concrete error type for errors encountered when reading and writing.

Required methods

fn print<T>(&mut self, message: T) -> Result<(), Self::Error> where
    T: AsRef<[u8]>, 

Writes the given bytes to the interpreter stdout stream.

Errors

If the output stream encounters an error, an error is returned.

Provided methods

fn puts<T>(&mut self, message: T) -> Result<(), Self::Error> where
    T: AsRef<[u8]>, 

Writes the given bytes to the interpreter stdout stream followed by a newline.

This default implementation uses two calls to Io::print.

Errors
