Struct rocksdb::SliceTransform

source ·
pub struct SliceTransform {
    pub inner: *mut rocksdb_slicetransform_t,
}
Expand description

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.
