Struct LutTarget 

pub struct LutTarget {
    pub input: String,
    pub output: String,
    pub handler_mod: String,
    pub ctx_type: String,
    pub dispatch: Dispatch,
    pub groups: HashMap<String, Vec<String>>,
    pub lut_mod: Option<String>,
    pub instr_type: Option<String>,
    pub raw_expr: Option<String>,
    pub instr_type_output: Option<String>,
    pub subdecoder_groups: HashMap<String, HashMap<String, Vec<String>>>,
}

A single emulator dispatch LUT generation target.

Fields

input: String

Path to the input .chipi file. Supports $VAR expansion and relative paths (resolved from the TOML file’s directory).

output: String

Output file path for the LUT dispatch code. Supports $VAR expansion (e.g. $OUT_DIR/lut.rs).

handler_mod: String

Rust module path where handler functions live.

ctx_type: String

Mutable context type passed to every handler.

dispatch: Dispatch

Dispatch strategy.

groups: HashMap<String, Vec<String>>

Instruction groups: group name -> list of instruction names. Instructions in a group share one const-generic handler function.

lut_mod: Option<String>

Rust module path where the generated OP_* constants live. Required when using groups so stubs can import the constants.

instr_type: Option<String>

Override the type of the second handler parameter (default: width-derived u8/u16/u32). Set to a wrapper type like "crate::cpu::Instruction".

raw_expr: Option<String>

Expression to extract the raw integer from the instr local. Default: "instr.0" when instr_type is set, "opcode" otherwise.

instr_type_output: Option<String>

Output file path for the instruction newtype with field accessors. Supports $VAR expansion. If set, generates a pub struct Name(pub u32) with accessor methods.

subdecoder_groups: HashMap<String, HashMap<String, Vec<String>>>

Sub-decoder groups: sub-decoder name -> { group name -> [instruction names] }. Instructions in a group share one const-generic handler function. If a sub-decoder is listed here, a dispatch_{snake_name} function is generated.
