Trait PresentableExt 

pub trait PresentableExt {
    // Required methods
    fn left_presentable<B>(self) -> Either<Self, B>
       where B: Presentable,
             Self: Sized;
    fn right_presentable<A>(self) -> Either<A, Self>
       where A: Presentable,
             Self: Sized;
}

Additional functionality for Presentable types.

Required Methods

fn left_presentable<B>(self) -> Either<Self, B>

where B: Presentable, Self: Sized,

Wraps this Presentable in an Either, making it the left-hand variant of that Either.

This can be used in combination with the right_presentable method to write if statements that evaluate to different Presentables in different branches.

Examples

use peace_fmt::{Either, Presentable, PresentableExt};

let cond = true;

let presentable = if cond {
    Bold::new(String::from("a")).left_presentable();
} else {
    CodeInline::new("b".into()).right_presentable();
};

presentln!(output, &presentable);

fn right_presentable<A>(self) -> Either<A, Self>

where A: Presentable, Self: Sized,

Wraps this Presentable in an Either, making it the right-hand variant of that Either.

This can be used in combination with the left_presentable method to write if statements that evaluate to different Presentables in different branches.

Examples

use peace_fmt::{Either, Presentable, PresentableExt};

let cond = true;

let presentable = if cond {
    Bold::new(String::from("a")).left_presentable();
} else {
    CodeInline::new("b".into()).right_presentable();
};

presentln!(output, &presentable);
