Trait Text 

pub trait Text<'a>:
    Sized
    + Clone
    + 'a {
    // Required methods
    fn from_static_str(s: &'static str) -> Self;
    fn as_str(&self) -> Cow<'_, str>;

    // Provided methods
    fn from_static_spaces(s: &'static str) -> Self { ... }
    fn len(&self) -> usize { ... }
    fn space() -> Self { ... }
    fn newline() -> Self { ... }
    fn comma_space() -> Self { ... }
}

Pretty printing can work with arbitrary text-like objects, as long as they implement this trait.

Required Methods

fn from_static_str(s: &'static str) -> Self

Turn a &’static str into Self, without any further knowledge about it.

Used for a bunch of functions to give a default. Often not the most optimal or even desired implementation.

fn as_str(&self) -> Cow<'_, str>

Turn custom text into a Cow<'a, str>.

Provided Methods

fn from_static_spaces(s: &'static str) -> Self

We foten insert spaces as a static str.

By default this is implemented with [from_static_str].

fn len(&self) -> usize

Get the length of the custom text.

fn space() -> Self

A space character

By default this is implemented with [from_static_str].

fn newline() -> Self

A newline character

By default this is implemented with [from_static_str].

fn comma_space() -> Self

A comma and space character

By default this is implemented with [from_static_str].

Dyn Compatibility

This trait is not dyn compatible.

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