Trait Iden

    // Required method
    fn unquoted(&self, s: &mut dyn Write);

    // Provided methods

Identifier

Required Methods

fn unquoted(&self, s: &mut dyn Write)

Write a raw identifier string without quotes.

We indentionally don’t reuse Display for this, because we want to allow it to have a different logic.

Provided Methods

fn prepare(&self, s: &mut dyn Write, q: Quote)

fn quoted(&self, q: Quote) -> String

fn to_string(&self) -> String

A shortcut for writing an unquoted identifier into a String.

We can’t reuse ToString for this, because ToString uses the Display representation. Bnd Iden representation is distinct from Display and can be different.
