pub struct SegmentId(_);
Expand description
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.
Implementations
sourceimpl SegmentId
impl SegmentId
sourcepub fn short_uuid_string(&self) -> String
pub fn short_uuid_string(&self) -> String
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 (e.g. a5c4dfcb).
sourcepub fn uuid_string(&self) -> String
pub fn uuid_string(&self) -> String
Returns a segment uuid string.
It consists in 32 lowercase hexadecimal chars (e.g. a5c4dfcbdfe645089129e308e26d5523)
sourcepub fn from_uuid_string(
uuid_string: &str
) -> Result<SegmentId, SegmentIdParseError>
pub fn from_uuid_string(
uuid_string: &str
) -> Result<SegmentId, SegmentIdParseError>
Build a SegmentId
string from the full uuid string.
E.g. “a5c4dfcbdfe645089129e308e26d5523”
