Function lualite::parser::atomic::identifier

pub fn identifier(s: &str) -> IResult<&str, Identifier>

Parser for identifiers

Ensures the first character is not a digit and the identifier is not a keyword.

Example:

assert!(identifier("x").is_ok()); // succeeds
assert!(identifier("foo_bar3").is_ok()); // succeeds
assert!(identifier("_unused_var").is_ok()); // succeeds
assert!(identifier("while").is_err()); // fails (while is a keyword)
assert!(identifier("7hello").is_err()); // fails (treated as integer literal)
