#[repr(transparent)]pub struct Braced(_);
Expand description
Format a Uuid
as a braced hyphenated string, like
{67e55044-10b1-426f-9247-bb680e5fe0c8}
.
Implementations
sourceimpl Braced
impl Braced
sourcepub fn encode_lower<'buf>(&self, buffer: &'buf mut [u8]) -> &'buf mut str
pub fn encode_lower<'buf>(&self, buffer: &'buf mut [u8]) -> &'buf mut str
Writes the Uuid
as a lower-case hyphenated string surrounded by
braces 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.braced()
.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.braced().encode_lower(&mut buf);
assert_eq!(
&buf as &[_],
b"{936da01f-9abd-4d9d-80c7-02af85c822a8}!!" as &[_]
);
Ok(())
}
