is_uuid

Checks whether s is a UUID in its canonical 8-4-4-4-12 hyphenated hexadecimal form.

Case-insensitive. The variant and version digits are not checked, so this accepts any RFC 9562 UUID (v1 through v8) as well as the all-zero nil UUID; it only checks the shape.

Import

use helpers4::validate::is_uuid;

Cargo feature validate (enabled by default). To compile only this module:

cargo add helpers4 --no-default-features --features validate

or in Cargo.toml:

[dependencies]
helpers4 = { version = "0.0.5", default-features = false, features = ["validate"] }

Signature

pub fn is_uuid(s: &str) -> bool

Parameters

Parameter	Type	Description
s	&str	The text to check.

Returns

bool — true when s has the shape of a UUID.

Examples

use helpers4::validate::is_uuid;

assert!(is_uuid("550e8400-e29b-41d4-a716-446655440000"));
assert!(is_uuid("550E8400-E29B-41D4-A716-446655440000"));
assert!(!is_uuid("550e8400-e29b-41d4-a716-44665544000")); // one digit short
assert!(!is_uuid("not-a-uuid"));
