CompressionBenchmark

oxirs_tdb::compression::benchmark

Struct CompressionBenchmark

pub struct CompressionBenchmark;

Expand description

Measures compression throughput and ratio for different algorithms.

All benchmarks are single-shot (not averaged); for statistical precision use the benchmarking feature with multiple iterations.

Implementations§

impl CompressionBenchmark

pub fn new() -> Self

Create a new CompressionBenchmark instance (stateless).

pub fn benchmark_algorithm( algo: CompressionAlgo, data: &[u8], ) -> BenchmarkResult

Benchmark a single algorithm on the given data.

Returns a BenchmarkResult regardless of whether compression succeeds: on error, ratio is set to 1.0 and throughputs to 0.0.

pub fn benchmark_all(data: &[u8]) -> Vec<BenchmarkResult>

Benchmark all supported algorithms on the given data.

Results are returned in algorithm order (Delta, RunLength, LZ4, Zstd, Snappy).

pub fn best_ratio(results: &[BenchmarkResult]) -> Option<&BenchmarkResult>

Return the result with the best compression ratio (lowest ratio value).

pub fn best_compress_speed( results: &[BenchmarkResult], ) -> Option<&BenchmarkResult>

Return the result with the highest compression throughput (MB/s).

pub fn best_decompress_speed( results: &[BenchmarkResult], ) -> Option<&BenchmarkResult>

Return the result with the highest decompression throughput (MB/s).

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<ST, DT> CastableFrom<ST, Initialized, Initialized> for DT
where ST: ?Sized, DT: ?Sized,

impl<ST, DT> CastableFrom<ST, Uninit, Uninit> for DT
where ST: ?Sized, DT: ?Sized,

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_sync(self: Box<T>) -> Box<dyn Any + Sync + Send>
