Examples

Parsing


let n_bytes: PartSizeBytes = "34".parse().unwrap();
assert_eq!(n_bytes, 34.into());

let n_bytes: PartSizeBytes = "1k".parse().unwrap();
assert_eq!(n_bytes, 1_000.into());

let n_bytes: PartSizeBytes = "1 k".parse().unwrap();
assert_eq!(n_bytes, 1_000.into());

let n_bytes: PartSizeBytes = "1M".parse().unwrap();
assert_eq!(n_bytes, 1_000_000.into());

let n_bytes: PartSizeBytes = "1G".parse().unwrap();
assert_eq!(n_bytes, 1_000_000_000.into());

let n_bytes: PartSizeBytes = "1Ki".parse().unwrap();
assert_eq!(n_bytes, 1_024.into());

let n_bytes: PartSizeBytes = "1Mi".parse().unwrap();
assert_eq!(n_bytes, 1_048_576.into());

let n_bytes: PartSizeBytes = "1Gi".parse().unwrap();
assert_eq!(n_bytes, 1_073_741_824.into());

// Case sensitive
let res = "1K".parse::<PartSizeBytes>();
assert!(res.is_err());

let res = "x".parse::<PartSizeBytes>();
assert!(res.is_err());

let res = "".parse::<PartSizeBytes>();
assert!(res.is_err());
