Module parse_integer_options 

Available on crate feature parse-integers only.

Configuration options for parsing integers.

Pre-Defined Formats

This contains pre-defined options optimized for either the parsing of large or small numbers.

• SMALL_NUMBERS: Optimize the parsing of small integers, at a major performance cost to larger values.
• LARGE_NUMBERS: Optimize the parsing of large integers, at a slight performance cost to smaller values.

Examples

use lexical_parse_integer::{FromLexicalWithOptions, Options};
use lexical_parse_integer::format::STANDARD;

const OPTIONS: Options = Options::builder()
    .no_multi_digit(true)
    .build_strict();

let value = "1234";
let result = u64::from_lexical_with_options::<STANDARD>(value.as_bytes(), &OPTIONS);
assert_eq!(result, Ok(1234));
