Struct Number 

pub struct Number<'a> {
    pub value: f64,
    pub lexeme: Option<&'a str>,
}

A number as the source spelled it and as a machine value.

lexeme is the source text when the source could hand it over (the rule-event adapter reads it off the token; the JSON Lines source likewise), else None, and the renderer falls back to the shortest round-trip form of value. Keeping both is how 50.25 stays 50.25 and how a number beyond f64’s exact range keeps its digits.

Fields

value: f64

lexeme: Option<&'a str>
