Struct Key 

pub struct Key {
    pub backend: Backend,
    pub op: &'static str,
    pub role: &'static str,
    pub kind: Option<QuantKind>,
    pub file: &'static str,
    pub line: u32,
}

The identity of one lookup. Deduplicated on this; a repeated lookup bumps Entry::count instead of adding a row.

Fields

backend: Backend

op: &'static str

See op.

role: &'static str

Tensor role ("attn_q", "ffn_down", "moe_router", …) or "(dispatch)" when recorded from the hot path, where the role is not known.

kind: Option<QuantKind>

None for a non-quantized (F32 / MXFP4-pair) matrix.

file: &'static str

line: u32
