Trait InputOutput 

pub trait InputOutput {
    // Required methods
    fn print(&self, text: &str) -> Result<(), Error>;
    fn println(&self, text: &str) -> Result<(), Error>;
    fn flush(&self) -> Result<(), Error>;
    fn read_line(&self) -> Result<String, Error>;
    fn read_line_with_timeout(&self, timeout: Duration) -> Result<String, Error>;
}

Trait abstraction for input/output operations to enable mocking

Required Methods

fn print(&self, text: &str) -> Result<(), Error>

Print text to output

Errors

Returns an error if the output operation fails

fn println(&self, text: &str) -> Result<(), Error>

Print text to output with newline

Errors

Returns an error if the output operation fails

fn flush(&self) -> Result<(), Error>

Flush output buffer

Errors

Returns an error if the flush operation fails

fn read_line(&self) -> Result<String, Error>

Read a line of input from user

Errors

Returns an error if the input operation fails

fn read_line_with_timeout(&self, timeout: Duration) -> Result<String, Error>

Read a line of input from user with timeout

Errors

Returns an error if the input operation fails or times out

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
