Struct PlaceholderFormat 

pub struct PlaceholderFormat { /* private fields */ }

A parsed placeholder template.

Rules: it contains {TYPE} and {N} once each, separated by literal text, and it starts and ends with literal text. The opening text must start with a character that is not a letter, digit or _, so placeholders can’t run into surrounding words.
