Expand description

CompressionAlgorithm specifies to use which algorithm to compress a block.

Variants

`None`

None mode indicates that a block is not compressed.

`Snappy`

Snappy mode indicates that a block is compressed using Snappy algorithm.

`Zstd`

ZSTD mode indicates that a block is compressed using ZSTD algorithm. ZSTD,

`Lz4`

Lz4 mode indicates that a block is compressed using lz4 algorithm.

Implementations

impl CompressionAlgorithm

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of CompressionAlgorithm.

pub fn from_i32(value: i32) -> Option<CompressionAlgorithm>

Converts an i32 to a CompressionAlgorithm, or None if value is not a valid variant.

impl CompressionAlgorithm

pub const fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.
