Struct rocksdb::DBPinnableSlice

pub struct DBPinnableSlice<'a> { /* fields omitted */ }

Wrapper around RocksDB PinnableSlice struct.

With a pinnable slice, we can directly leverage in-memory data within RocksDB toa void unnecessary memory copies. The struct here wraps the returned raw pointer and ensures proper finalization work.

Methods

impl<'a> DBPinnableSlice<'a>

pub unsafe fn from_c(ptr: *mut rocksdb_pinnableslice_t) -> DBPinnableSlice<'a>

Used to wrap a PinnableSlice from rocksdb to avoid unnecessary memcpy

Unsafe

Requires that the pointer must be generated by rocksdb_get_pinned
