Enum HostTable 

pub enum HostTable {
    Rotary(RotaryTable),
    Temperature {
        cached: bool,
        cos: bool,
        half: usize,
    },
    Ones(usize),
}

A table the host computes from the spec rather than reads from the checkpoint.

Variants

Rotary(RotaryTable)

A rotation’s cosines or sines (RotaryTable).

Temperature

Llama 4’s attention temperature as a rotation of half pairs: cosines Temperature::at(p) at every pair, sines zero — a decode step’s caches (cached, row p for position p) or a forward’s one row (position 0). Read by the rope sugar, it scales each query row by its own position’s factor.

Fields

cached: bool

cos: bool

half: usize

Ones(usize)

A row of n ones: the weight of an RMSNorm that has none (Llama 4’s QK norm), and the row a shared expert’s gate is spread across (Qwen’s mixtures).

Implementations

impl HostTable

pub fn name(self) -> String

The table’s declared name: a rotary table’s own, Tcos{half}/Tsin{half} (a forward’s TC{half}/TS{half}), Ones{n}.

pub fn named(name: &str) -> Option<HostTable>

The table name names, when it names one.

Trait Implementations

impl Clone for HostTable

fn clone(&self) -> HostTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostTable

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

Formats the value using the given formatter.

impl PartialEq for HostTable

fn eq(&self, other: &HostTable) -> 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.
