Struct RuleMeta 

#[repr(C)]
pub struct RuleMeta {
    pub transition_base: u32,
    pub accept_base: u32,
    pub state_count: u32,
    pub class_map_base: u32,
    pub num_classes: u32,
}

Packed metadata for one byte-class-compressed DFA rule entry.

The on-device transition table is transitions[transition_base + state * num_classes + class_maps[class_map_base + byte]]: each rule carries a 256-entry byte→class map (into the shared class_maps buffer) and a compressed state_count * num_classes transition block, instead of a dense state_count * 256 block. The compression is LOSSLESS, bytes share a class only when their transition column is identical across every state, so GPU firings are byte-for-byte identical to the dense table.

Fields

transition_base: u32

Word offset into the flattened (compressed) transition table.

accept_base: u32

Word offset into the flattened accept table.

state_count: u32

DFA state count for this rule.

class_map_base: u32

Word offset into the shared 256-entry-per-rule byte→class map table.

num_classes: u32

Number of distinct byte classes for this rule (the compressed row width).
