Trait StringBuilder 

pub trait StringBuilder<'a>: Sized {
    // Required methods
    fn push_str(&mut self, s: &'a str);
    fn push_char(&mut self, c: char);
    fn from_str(s: &'a str) -> Self;

    // Provided method
    fn empty() -> Self { ... }
}

Helper trait for parsing strings with escape sequences. Allows for returning borrowed strings without any allocation if there are no escape sequences, or for recognizing strings without doing actual parsing / allocation.

Required Methods

fn push_str(&mut self, s: &'a str)

Add a borrowed string to the back of this string

fn push_char(&mut self, c: char)

Add a char to the back of this string

fn from_str(s: &'a str) -> Self

Create a new instance from a borrowed string

Provided Methods

fn empty() -> Self

Create a new empty instance

Dyn Compatibility

This trait is not dyn compatible.

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

Implementations on Foreign Types

impl<'a> StringBuilder<'a> for ()

The empty tuple can be used as a string builder in cases where it’s only necessary to recognize a string and not to parse it

fn push_str(&mut self, _s: &'a str)

fn push_char(&mut self, _c: char)

fn from_str(_s: &'a str)

impl<'a> StringBuilder<'a> for String

Strings can, of course, be built

fn push_str(&mut self, s: &'a str)

fn push_char(&mut self, c: char)

fn from_str(s: &'a str) -> Self
