Struct ItemId 

pub struct ItemId { /* private fields */ }

PBI stable identifier (<PREFIX>-<NUMBER>, e.g. T-1).

Implementations

impl ItemId

pub fn try_new(prefix: impl Into<String>, number: u32) -> Result<Self>

Construct an ID from a validated prefix and number.

Prefixes are ASCII letters only. Use this fallible constructor at public boundaries; the crate-private constructor below is reserved for known-safe fixtures and values produced by already-validated domain data.

Examples

use pinto::backlog::ItemId;

let id = ItemId::try_new("T", 42).expect("safe prefix");
assert_eq!(id.prefix(), "T");
assert_eq!(id.number(), 42);
assert_eq!(id.to_string(), "T-42");

pub fn prefix(&self) -> &str

Prefix (e.g. T).

pub fn number(&self) -> u32

Serial number.
