Struct PlainEncoder 

pub struct PlainEncoder;

Plain (uncompressed) encoder.

Implementations

impl PlainEncoder

pub fn encode_f64(values: &[f64]) -> Result<Vec<u8>>

Encode f64 values uncompressed.

Errors

Returns EncodingError::EmptyInput if values is empty.

pub fn encode_i64(values: &[i64]) -> Result<Vec<u8>>

Encode i64 values uncompressed.

Errors

Returns EncodingError::EmptyInput if values is empty.

pub fn encode_u64(values: &[u64]) -> Result<Vec<u8>>

Encode u64 values uncompressed.

Errors

Returns EncodingError::EmptyInput if values is empty.

pub fn encode_bool(values: &[bool]) -> Result<Vec<u8>>

Encode boolean values uncompressed (1 byte per bool).

Errors

Returns EncodingError::EmptyInput if values is empty.

pub fn encode_string(values: &[&str]) -> Result<Vec<u8>>

Encode string values uncompressed (length-prefixed).

Errors

Returns EncodingError::EmptyInput if values is empty.

pub fn encode_bytes(values: &[&[u8]]) -> Result<Vec<u8>>

Encode a byte-string column.

The same wire shape as encode_string — a count, then a u32 length and that many bytes per value — without the UTF-8 constraint. It exists for native histograms, whose values are composite objects with no numeric representation to compress.

Errors

EncodingError::EmptyInput for no values, or EncodingError::CorruptData for a value longer than u32::MAX.
