Struct CompressedBlock 

pub struct CompressedBlock {
    pub algorithm: CompressionAlgorithm,
    pub data: Vec<u8>,
    pub sample_count: u32,
    pub min_timestamp: i64,
    pub max_timestamp: i64,
}

A self-describing compressed block holding one or more time-series samples.

Fields

algorithm: CompressionAlgorithm

The algorithm used to produce this block.

data: Vec<u8>

Raw compressed bytes.

sample_count: u32

Number of samples encoded in this block.

min_timestamp: i64

Timestamp of the first sample (ms since epoch).

max_timestamp: i64

Timestamp of the last sample (ms since epoch).

Implementations

impl CompressedBlock

pub fn compression_ratio(&self) -> f64

Approximate compression ratio: original_bytes / compressed_bytes.

pub fn decode(&self) -> TsdbResult<Vec<(i64, f64)>>

Decode the block back to (timestamp_ms, value) pairs.
