Struct RvGasMeta 

pub struct RvGasMeta {
    pub kind: u8,
    pub src1_slot: u8,
    pub src2_slot: u8,
    pub dst_slot: u8,
}

Pre-resolved metadata used by the per-block gas accountant. The fields are computed once at decode time so the gas hot path does not have to re-match the Inst variant on each invocation.

• kind is an index into gas_cost::RV_GAS_COST_LUT.
• src1_slot/src2_slot/dst_slot are PVM2 register slots (0..12, ordered x1, x2, x5..x15) or 0xFF for “no register” (x0, x3, x4, or an unused register slot for this opcode).

Fields

kind: u8

src1_slot: u8

src2_slot: u8

dst_slot: u8
