Function parse_with

pub fn parse_with<T>(
    range_str: &str,
    value_separator: &str,
    range_separator: &str,
) -> RangeResult<Vec<T>>
where

Expand description

Parse a range string to a vector of any kind of numbers with custom separators

The type T must implement the FromStr, Add, PartialEq, PartialOrd, Unit and Copy traits.

§Arguments

  • range_str: &str - the range string to parse
  • value_separator: &str - the separator for single values
  • range_separator: &str - the separator for ranges

§Returns

  • Result<Vec, RangeError> - the parsed range

§Ambiguous separators

The range separator cannot be the same as the value separator, and it cannot be one of the following: --, because it’s ambiguous since it couldn’t resolve negative numbers.

§Example

let range: Vec<i32> = range_parser::parse_with::<i32>("0;3;5..8;-1", ";", "..").unwrap();
assert_eq!(range, vec![0, 3, 5, 6, 7, 8, -1]);
