Enum FrameSlot 

pub enum FrameSlot {
    Narrow4State {
        word_count: u16,
    },
    Wide4State {
        aval_word_count: u32,
        bval_word_count: u32,
    },
    Array {
        rows: u32,
        row_words: u16,
    },
}

One frame slot’s compile-time SHAPE only (process.md §3 FrameSlot/ FourStateI2N/WideFourState; ledger ST-103..ST-105): the number of u64 words the slot’s payload occupies. This is layout metadata CODEGEN consumes when computing a TEMPLATE’s fixed frame offsets (“Frame slot layout is decided once per process TEMPLATE… handed to codegen as a fixed struct layout”) — never the runtime payload itself, which is why it carries counts, not Vec<u64> data (see ActivationRecord’s doc comment for why that distinction is load-bearing).

Variants

Narrow4State

Fields

word_count: u16

Wide4State

Fields

aval_word_count: u32

Array

A fixed-size unpacked-array local: rows rows (all dimensions flattened, lowest index first) of row_words words each, a row holding one element’s packed value.
