Available on crate feature uuid only.
Expand description

Format a Uuid as a simple string, like 67e5504410b1426f9247bb680e5fe0c8.

Implementations

The length of a simple Uuid string.

Creates a Simple from a Uuid.

Writes the Uuid as a lower-case simple string to buffer, and returns the subslice of the buffer that contains the encoded UUID.

This is slightly more efficient than using the formatting infrastructure as it avoids virtual calls, and may avoid double buffering.

Panics

Panics if the buffer is not large enough: it must have length at least LENGTH. Uuid::encode_buffer can be used to get a sufficiently-large temporary buffer.

Examples
use uuid::Uuid;

fn main() -> Result<(), uuid::Error> {
    let uuid = Uuid::parse_str("936DA01f9abd4d9d80c702af85c822a8")?;

    // the encoded portion is returned
    assert_eq!(
        uuid.simple().encode_lower(&mut Uuid::encode_buffer()),
        "936da01f9abd4d9d80c702af85c822a8"
    );

    // the buffer is mutated directly, and trailing contents remains
    let mut buf = [b'!'; 36];
    assert_eq!(
        uuid.simple().encode_lower(&mut buf),
        "936da01f9abd4d9d80c702af85c822a8"
    );
    assert_eq!(
        &buf as &[_],
        b"936da01f9abd4d9d80c702af85c822a8!!!!" as &[_]
    );

    Ok(())
}

Get a reference to the underlying Uuid.

Examples
use uuid::Uuid;

let simple = Uuid::nil().simple();
assert_eq!(*simple.as_uuid(), Uuid::nil());

Consumes the Simple, returning the underlying Uuid.

Examples
use uuid::Uuid;

let simple = Uuid::nil().simple();
assert_eq!(simple.into_uuid(), Uuid::nil());
