Trait TryRead

pub trait TryRead {
    type Output;
    type Default;

    // Required method
    fn try_read_line(
        self,
        prompt: Option<String>,
        default: Option<Self::Default>,
    ) -> BoxResult<Self::Output>;
}

This is what powers the whole crate. Any type that implements this can be used with the macros

Required Associated Types

type Output

Defines the output type of read and prompt macros

type Default

Defines the type of the default input

Required Methods

fn try_read_line( self, prompt: Option<String>, default: Option<Self::Default>, ) -> BoxResult<Self::Output>

This is what’s called by the read and prompt macros
