Validate a ULID

See more ULID/UUID Examples

Checks to see if a ULID is valid.

Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

Rust

let dt = chilkat::DateTime::new();

// A ULID must be exactly 26 chars in length,
// and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
// Note: The ULID alphabet excludes the letters I, L, O, and U

// Here's a valid ULID
let mut ulid = "01GRGCH4J88RECEN4D4VK4F629".to_string();
let mut valid = dt.ulid_validate(&ulid).is_ok();
println!("valid: {}", valid);

// Here's an invalid ULID
ulid = "71GRGxx4Jr8RECEN4D4VK4F62!".to_string();
valid = dt.ulid_validate(&ulid).is_ok();
println!("valid: {}", valid);
