Struct Coded 

pub struct Coded<'a> { /* private fields */ }

The codes of a compressed column and the table they are against.

Handed out by Vector::coded_parts so a kernel can work in code space. Nothing here decompresses, which is the point: Self::encode puts the literal into the same space the rows are already in, and after that an equality test is a byte slice comparison.

Implementations

impl Coded<'_>

pub fn table(&self) -> &SymbolTable

The table every row in this vector is compressed against.

pub fn row(&self, row: usize) -> Option<&[u8]>

The code bytes of one row, still compressed.

pub fn encode(&self, bytes: &[u8]) -> Vec<u8>

Some bytes in the code space this vector is in.

The literal side of an equality filter. Compressing is a function of the table and the bytes, so two strings compress to the same codes exactly when they are the same string, and an equality test on the codes is an equality test on the strings with no decompression in it.
