Compression codec type

Variants§

§

None

No compression

§

Rle

§

Delta

Delta encoding (best for sorted/sequential data)

§

Dictionary

Dictionary encoding (best for low cardinality)

§

BitPack

Bit-packing (best for small integers)

Trait Implementations§

Source§

impl Clone for Codec

Source§

fn clone(&self) -> Codec

Returns a duplicate of the value. Read more
1.0.0§

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

Performs copy-assignment from source. Read more

impl Debug for Codec

Source§

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

Source§

impl PartialEq for Codec

Source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0§

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

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