Struct SlotData 

pub struct SlotData { /* private fields */ }

Dense Vec indexed by slot_id — the bridge between Rust page handlers and the IR walker.

Handlers create a SlotData, populate it with values (title, user name, nav items, etc.), then the walker reads slot values when it encounters DYN_TEXT, DYN_ATTR, SHOW_IF, LIST opcodes.

Implementations

impl SlotData

pub fn new(capacity: usize) -> Self

Create a new SlotData with capacity Null-initialized slots.

pub fn set(&mut self, slot_id: u16, value: SlotValue)

Set a slot value. No-op if slot_id is out of bounds.

pub fn get(&self, slot_id: u16) -> &SlotValue

Get a reference to a slot value. Returns &Null if out of bounds.

pub fn get_text(&self, slot_id: u16) -> Option<&str>

Get the text content of a slot. Returns Some(&str) if Text, None otherwise.

pub fn from_json(json_str: &str, module: &IrModule) -> Result<Self, IrError>

Create SlotData from a named-key JSON string, resolving names to slot IDs via the module’s string table and slot table.

The JSON must be an object (e.g., {"title": "Hello", "count": 42}). Each key is resolved against the slot table: the slot entry’s name_str_idx is looked up in the string table to find the slot name. If it matches a JSON key, the JSON value is converted to a SlotValue and stored at that slot_id.

Unknown JSON keys (not in the slot table) are silently ignored. Starts from slot table defaults so missing keys retain their defaults.

pub fn new_from_defaults(table: &SlotTable) -> Self

Create SlotData pre-populated from the IR slot table defaults. Server-sourced slots with no default -> Null. Client-sourced slots with defaults -> parsed from default_bytes.

Trait Implementations

fn clone(&self) -> SlotData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SlotData

fn fmt(&self, f: &mut Formatter<'_>) -> Result
