Trait Writer 

pub trait Writer {
    // Required methods
    fn start(&mut self) -> Result<()>;
    fn finish(&mut self) -> Result<()>;
    fn write_i32(&mut self, n: i32) -> Result<()>;

}

Required Methods

fn start(&mut self) -> Result<()>

fn finish(&mut self) -> Result<()>

fn write_i32(&mut self, n: i32) -> Result<()>

fn write_f32(&mut self, n: f32) -> Result<()>

fn write_f64(&mut self, n: f64) -> Result<()>

fn write_bool(&mut self, n: bool) -> Result<()>

fn write_str(&mut self, str: &[u8]) -> Result<()>

Dyn Compatibility

This trait is dyn compatible.

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