Trait IoOutput 

pub trait IoOutput {
    type Error;

    // Required method
    async fn write(&mut self, value: &str) -> Result<(), Self::Error>;
}

The raw IO output.

This trait is not implemented by the library in a concrete way. Instead, depending on which async runtime you are using, you will have to implement it yourself.

Required Associated Types

type Error

The error type for write operations

Required Methods

async fn write(&mut self, value: &str) -> Result<(), Self::Error>

Writes a string to the output. Yields an error upon failure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<'o, O> IoOutput for &'o mut O

where O: IoOutput,

type Error = <O as IoOutput>::Error

async fn write(&mut self, value: &str) -> Result<(), Self::Error>
