Struct rocksdb::SliceTransform [−][src]
pub struct SliceTransform {
pub inner: *mut rocksdb_slicetransform_t,
}A SliceTransform is a generic pluggable way of transforming one string
to another. Its primary use-case is in configuring rocksdb
to store prefix blooms by setting prefix_extractor in
ColumnFamilyOptions.
