Struct FastCost

pub struct FastCost {
    pub cycles: u8,
    pub decode_slots: u8,
    pub exec_unit: u8,
    pub src_mask: u16,
    pub dst_mask: u16,
    pub is_terminator: bool,
    pub is_move_reg: bool,
}

Expand description

FastCost is the per-instruction analysis the gas simulator consumes. Cycles, decode slots, exec-unit class, src/dst register masks. is_terminator marks gas-block-ending instructions.
