Struct StdIoProvider 

pub struct StdIoProvider { /* private fields */ }

An IoProvider implementation backed by Rust’s standard I/O.

Supports the three well-known ports:

PortId	Direction	Backing
STDIN	input	std::io::stdin()
STDOUT	output	std::io::stdout()
STDERR	output	std::io::stderr()

Additionally supports dynamically opened string ports.

Implementations

impl StdIoProvider

pub fn new() -> Self

impl IoProvider for StdIoProvider

fn read_char(&mut self, port: PortId) -> IoResult<char>

Read a single character from the specified input port.

fn peek_char(&mut self, port: PortId) -> IoResult<char>

Peek at the next character without consuming it.

fn char_ready(&mut self, port: PortId) -> IoResult<bool>

Return true if a character is ready on the input port.

fn write_char(&mut self, port: PortId, c: char) -> IoResult<()>

Write a single character to the specified output port.

fn write_str(&mut self, port: PortId, s: &str) -> IoResult<()>

Write a string slice to the specified output port.

fn flush(&mut self, port: PortId) -> IoResult<()>

Flush the specified output port.

fn close_port(&mut self, port: PortId) -> IoResult<()>

Close the specified port.

fn is_input_port(&self, port: PortId) -> bool

Return true if the port is an input port.

fn is_output_port(&self, port: PortId) -> bool

Return true if the port is an output port.

fn open_input_string(&mut self, s: &str) -> IoResult<PortId>

Open an input port that reads from the given string.

fn open_output_string(&mut self) -> IoResult<PortId>

Open an output port that accumulates characters into a string buffer.

fn get_output_string(&self, port: PortId) -> IoResult<&str>

Retrieve the accumulated string from an output string port.
