Trait Format 

Source 
pub trait Format {
    // Required methods
    fn nonterminal_delimiter() -> Option<(char, char)>;
    fn production_separator() -> &'static str;
    fn alternative_separator() -> char;

    // Provided method
    fn production_start_char() -> Option<char> { ... }
}

Required Methods§

Source

fn nonterminal_delimiter() -> Option<(char, char)>

Source

fn production_separator() -> &'static str

Source

fn alternative_separator() -> char

Provided Methods§

Source

fn production_start_char() -> Option<char>

If Some(c), production boundaries can be detected by this character after whitespace (e.g. BNF uses '<'), avoiding a full prod_lhs parse as lookahead.

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.
