Struct FseTableEntry 

pub struct FseTableEntry {
    pub baseline: u16,
    pub num_bits: u8,
    pub symbol: u8,
    pub seq_base: u32,
    pub seq_extra_bits: u8,
    /* private fields */
}

A single entry in an FSE decoding table.

For sequence tables (LL, ML, OF), this includes direct decoding fields that store the sequence baseline and extra bits count directly, matching zstd’s production decoder tables.

Fields

baseline: u16

Base value to add to the read bits to get the next state.

num_bits: u8

Number of bits to read from the bitstream for the next state.

symbol: u8

The symbol this state decodes to (e.g., ML code, LL code, OF code).

seq_base: u32

For sequences: direct base value for the decoded length/offset. This allows bypassing the symbol → baseline lookup for optimized decoding.

seq_extra_bits: u8

For sequences: number of extra bits to read for this entry.

Implementations

impl FseTableEntry

pub const fn new(symbol: u8, num_bits: u8, baseline: u16) -> Self

Create a new FSE table entry.

pub const fn new_seq( symbol: u8, num_bits: u8, baseline: u16, seq_base: u32, seq_extra_bits: u8, ) -> Self

Create a new FSE table entry with direct sequence decoding values. Used for predefined sequence tables that store baseValue directly.

Trait Implementations

impl Clone for FseTableEntry

fn clone(&self) -> FseTableEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FseTableEntry

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

Formats the value using the given formatter.

impl Default for FseTableEntry

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FseTableEntry

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

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

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

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