Trait StdOut 

pub trait StdOut: Send + 'static {
    // Required methods
    fn write_bytes(&self, bytes: &[u8]) -> Result;
    fn write_str(&self, s: &str) -> Result;
    fn write_fmt(&self, args: Arguments<'_>) -> Result;
    fn flush(&self) -> Result;
}

A trait describes common operations with the stdout.

Required Methods

fn write_bytes(&self, bytes: &[u8]) -> Result

Writes a bytes slice into the stdout, returning whether write succeeded.

fn write_str(&self, s: &str) -> Result

Writes a string slice.

fn write_fmt(&self, args: Arguments<'_>) -> Result

Writes a formatted string.

fn flush(&self) -> Result

Ensures that none of the previously written bytes are still buffered.

Dyn Compatibility

This trait is dyn compatible.

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