Function non_std::dependencies::strs_tools::string::number::protected::parse_with_options

pub fn parse_with_options<N, Bytes, const FORMAT: u128>(
    bytes: Bytes, 
    options: &<N as FromLexicalWithOptions>::Options
) -> Result<N, Error> where
    N: FromLexicalWithOptions,
    Bytes: AsRef<[u8]>, 

High-level conversion of bytes to a number with custom parsing options.

This function only returns a value if the entire string is successfully parsed.

• FORMAT - Packed struct containing the number format.
• bytes - Byte slice to convert to number.
• options - Options to specify number parsing.

Panics

If the provided FORMAT is not valid, the function may panic. Please ensure is_valid() is called prior to using the format, or checking its validity using a static assertion.

Examples

const FORMAT: u128 = lexical::format::STANDARD;
let options = lexical::ParseFloatOptions::builder()
    .exponent(b'^')
    .decimal_point(b',')
    .build()
    .unwrap();
assert_eq!(lexical::parse_with_options::<f32, _, FORMAT>("0", &options), Ok(0.0));
assert_eq!(lexical::parse_with_options::<f32, _, FORMAT>("1,2345", &options), Ok(1.2345));
assert_eq!(lexical::parse_with_options::<f32, _, FORMAT>("1,2345^4", &options), Ok(12345.0));
