Trait StrWrite 

pub trait StrWrite {
    type Error;

    // Required methods
    fn write_str(&mut self, s: &str) -> Result<(), Self::Error>;
    fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Self::Error>;
}

Trait that allows writing string slices. This is basically an extension of std::io::Write in order to include String.

Required Associated Types

type Error

Required Methods

fn write_str(&mut self, s: &str) -> Result<(), Self::Error>

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

Dyn Compatibility

This trait is dyn compatible.

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