FromPest

✓ use from_pest::FromPest;

Define a pest grammar for numbers and convert parsed pairs into a typed AST struct.

use from_pest::FromPest; use pest::Parser; #[derive(Parser)] #[grammar_inline = "number = { ASCII_DIGIT+ }"] struct MyParser; #[derive(FromPest)] struct Number(String); fn main() { let pairs = MyParser::parse(Rule::number, "42").unwrap(); let number = Number::from_pest(&pairs).unwrap(); println!("Parsed number: {}", number.0); }

Debug
