Struct TraceFilter 

pub struct TraceFilter(/* private fields */);

Which operation types tracing skips.

Every bit excludes an operation type from the trace, so TraceFilter::empty traces everything and TraceFilter::GET | TraceFilter::MULTI_GET traces everything except point lookups. Filtering happens before sampling.

Mirrors TraceFilterType in include/rocksdb/options.h. Bits that this version of RocksDB does not define are preserved rather than rejected, so a value read back from TraceOptions::get_filter always round-trips.

Implementations

impl TraceFilter

pub const NONE: Self

Exclude nothing, the RocksDB default.

pub const GET: Self

Exclude Get.

pub const WRITE: Self

Exclude writes.

pub const ITERATOR_SEEK: Self

Exclude Iterator::Seek.

pub const ITERATOR_SEEK_FOR_PREV: Self

Exclude Iterator::SeekForPrev.

pub const MULTI_GET: Self

Exclude MultiGet.

pub const fn empty() -> Self

A filter that excludes nothing, the same as TraceFilter::NONE.

pub const fn bits(self) -> u64

The raw bitmask, as RocksDB stores it.

pub const fn from_bits_retain(bits: u64) -> Self

Builds a filter from a raw bitmask, keeping bits this crate does not know about instead of dropping them.

pub const fn contains(self, other: Self) -> bool

Whether every bit set in other is also set here. Always true when other is empty.
