Trait WriteStr 

pub trait WriteStr {
    type Output;

    // Required method
    fn write_str(&mut self, buf: &str) -> Self::Output;
}

A trait for objects which can write str returning a specific output.

This trait is used by FmtWriter and ConcatWriter writers.

Required Associated Types

type Output

The resulting type after writing.

Required Methods

fn write_str(&mut self, buf: &str) -> Self::Output

Performs byte writing.

Dyn Compatibility

This trait is dyn compatible.

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