Required methods

pub 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

pub 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

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

Implementors

impl Io for Artichoke

type Error = Error

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

Writes the given bytes to the interpreter stdout stream.

This implementation delegates to the underlying output strategy.

Errors

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

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

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

This implementation delegates to the underlying output strategy.

Errors

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