Struct CompressionFieldParams 

pub struct CompressionFieldParams {
    pub rle_threshold: Option<f64>,
    pub compression: Option<String>,
    pub compression_level: Option<i32>,
    pub bss: Option<BssMode>,
}

Field-level compression parameters

Fields

rle_threshold: Option<f64>

RLE threshold (0.0-1.0) When run_count < num_values * threshold, RLE will be used

compression: Option<String>

General compression scheme: “lz4”, “zstd”, “none”

compression_level: Option<i32>

Compression level (only for schemes that support it, e.g., zstd)

bss: Option<BssMode>

Byte stream split mode for floating point data

Implementations

impl CompressionFieldParams

pub fn merge(&mut self, other: &Self)

Merge another CompressionFieldParams, non-None values will override

Trait Implementations

impl Clone for CompressionFieldParams

fn clone(&self) -> CompressionFieldParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionFieldParams

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

Formats the value using the given formatter.

impl Default for CompressionFieldParams

fn default() -> CompressionFieldParams

Returns the “default value” for a type.

impl PartialEq for CompressionFieldParams

fn eq(&self, other: &CompressionFieldParams) -> 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.
