Trait Escaper

pub trait Escaper: Copy {
    // Required method
    fn write_escaped_str<W: Write>(&self, dest: W, string: &str) -> Result;

    // Provided method
    fn write_escaped_char<W: Write>(&self, dest: W, c: char) -> Result { ... }
}

Escapers are used to make generated text safe for printing in some context.

E.g. in an Html context, any and all generated text can be used in HTML/XML text nodes and attributes, without for for maliciously injected data.

Required Methods

fn write_escaped_str<W: Write>(&self, dest: W, string: &str) -> Result

Escaped the input string string into dest

Provided Methods

fn write_escaped_char<W: Write>(&self, dest: W, c: char) -> Result

Escaped the input char c into dest

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.
