Crate use_id_prefix 

use-id-prefix

Prefixed identifier parsing and formatting helpers for RustUse.

Install

[dependencies]
use-id-prefix = "0.0.1"

Foundation

use-id-prefix models prefixes such as usr, org, repo, and evt, then composes them with validated identifier bodies using a fixed prefix_value shape.

Example

use use_id_prefix::{PrefixedId, PrefixedIdentifierKind, TypedPrefixedId};

struct User;

impl PrefixedIdentifierKind for User {
    const PREFIX: &'static str = "usr";
}

let parsed = PrefixedId::parse("usr_123")?;
let typed = TypedPrefixedId::<User>::new("123")?;

assert_eq!(parsed.to_string(), "usr_123");
assert_eq!(typed.to_string(), "usr_123");

When to use directly

Choose use-id-prefix when prefix parsing and formatting are the only identifier concern you need.

Scope

• Prefixes stay lowercase ASCII with optional digits after the first character.
• Values stay lightweight and string-backed.
• Registry lookup and storage policies are out of scope.

Status

use-id-prefix is a pre-1.0 crate with a narrow prefixed-ID API. Prefixed identifier helpers.
