Struct KeyValue 

pub struct KeyValue<'a, K> {
    pub key: K,
    pub value: &'a str,
}

Auxiliary struct for parsing key-value pairs.

Fields

key: K

Should be of any type that implements FromStr.

value: &'a str

The whitespace-trimmed content after the colon (:).

Implementations

impl<'a, K: FromStr> KeyValue<'a, K>

pub fn parse(s: &'a str) -> Result<Self, K::Err>

Create a new KeyValue pair by splitting on the first : and parsing the key.

Example

use rosu_map::util::KeyValue;
use rosu_map::section::difficulty::DifficultyKey;

let line = "ApproachRate: 9.3 // Some comment";

let kv = KeyValue::<DifficultyKey>::parse(line).unwrap();

assert_eq!(kv.key, DifficultyKey::ApproachRate);
assert_eq!(kv.value, "9.3 // Some comment");
