Struct FileChecksumGenFactory 

pub struct FileChecksumGenFactory { /* private fields */ }

A factory RocksDB asks for a checksum generator each time it creates an SST file.

Install one with Options::set_file_checksum_gen_factory. The setter copies the underlying shared_ptr, so a factory can be installed on any number of Options and dropped as soon as the last call returns.

Implementations

impl FileChecksumGenFactory

pub fn crc32c() -> Self

The built in CRC32C generator, recorded in the manifest under the name FileChecksumCrc32c.

Upstream notes that this digest is big endian and unmasked, unlike the other CRC32C values RocksDB computes, which makes it comparable with CRC32C implementations outside RocksDB.

Wraps GetFileChecksumGenCrc32cFactory.

Trait Implementations

impl Drop for FileChecksumGenFactory

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
