Enum CompressionAlgorithm 

pub enum CompressionAlgorithm {
    None,
    Snappy,
    Lz4,
    Zstd,
    Brotli,
}

Compression algorithm selection.

Maps to Parquet’s native compression codecs. All algorithms are included via parquet crate default features — no extra dependencies needed.

Variants

None

No compression — fastest writes, largest files.

Snappy

Snappy — fast compression/decompression, moderate ratio. Default algorithm. Speed: 250-500 MB/s compress, 500-1500 MB/s decompress.

Lz4

LZ4 — ultra-fast compression, comparable ratio to Snappy. Best for latency-sensitive and streaming workloads.

Zstd

Zstandard — excellent compression ratio with configurable levels (1-22). Best for archival, cold storage, and batch analytics.

Brotli

Brotli — maximum compression ratio with configurable levels (0-11). Best for web deployment and network transfer.

Implementations

impl CompressionAlgorithm

pub const ALL: &'static [CompressionAlgorithm]

All supported compression algorithms for enumeration/benchmarks.

Trait Implementations

impl Clone for CompressionAlgorithm

fn clone(&self) -> CompressionAlgorithm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompressionAlgorithm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CompressionAlgorithm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for CompressionAlgorithm

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CompressionAlgorithm

fn eq(&self, other: &CompressionAlgorithm) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
