Struct tantivy::SegmentId
[−]
[src]
pub struct SegmentId(_);
Uuid identifying a segment.
Tantivy's segment are identified by a UUID which is used to prefix the filenames of all of the file associated with the segment.
In unit test, for reproducability, the SegmentId
are
simply generated in an autoincrement fashion.
Methods
impl SegmentId
[src]
pub fn short_uuid_string(&self) -> String
[src]
Returns a shorter identifier of the segment.
We are using UUID4, so only 6 bits are fixed, and the rest is random.
Picking the first 8 chars is ok to identify segments in a display message.
pub fn uuid_string(&self) -> String
[src]
Returns a segment uuid string.
