Struct CacheMeta 

pub struct CacheMeta {
    pub page_size_tokens: u32,
    pub n_layers: u32,
    pub n_heads: u32,
    pub head_dim: u32,
    pub dtype: Dtype,
}

Static metadata describing a paged KV cache. Identical across pages of the same engine instance; embedded once in the PageManifest.

Fields

page_size_tokens: u32

Tokens per page (vLLM default 16).

n_layers: u32

Number of transformer layers.

n_heads: u32

Number of attention heads.

head_dim: u32

Per-head dimension.

dtype: Dtype

Numeric dtype.

Implementations

impl CacheMeta

pub const fn page_bytes(&self) -> usize

Bytes per K-page (or per V-page; they’re the same shape).

Trait Implementations

impl Clone for CacheMeta

fn clone(&self) -> CacheMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheMeta

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CacheMeta

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CacheMeta

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

impl Serialize for CacheMeta

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
