[][src]Struct uuid::adapter::Hyphenated

pub struct Hyphenated(_);

An adaptor for formatting an Uuid as a hyphenated string.

Takes an owned instance of the Uuid.

Methods

impl Hyphenated[src]

pub const LENGTH: usize[src]

The length of a hyphenated Uuid string.

pub const fn from_uuid(uuid: Uuid) -> Self[src]

Creates a Hyphenated from a Uuid.

pub fn encode_lower<'buf>(&self, buffer: &'buf mut [u8]) -> &'buf mut str[src]

Writes the Uuid as a lower-case hyphenated 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;

let uuid = Uuid::parse_str("936DA01f9abd4d9d80c702af85c822a8").unwrap();

// the encoded portion is returned
assert_eq!(
    uuid.to_hyphenated()
        .encode_lower(&mut Uuid::encode_buffer()),
    "936da01f-9abd-4d9d-80c7-02af85c822a8"
);

// the buffer is mutated directly, and trailing contents remains
let mut buf = [b'!'; 40];
uuid.to_hyphenated().encode_lower(&mut buf);
assert_eq!(
    &buf as &[_],
    b"936da01f-9abd-4d9d-80c7-02af85c822a8!!!!" as &[_]
);
