Struct RegisterNode 

pub struct RegisterNode {
    pub name: String,
    pub meta: NodeMeta,
    pub addressing: Addressing,
    pub access: AccessMode,
    pub port: Option<String>,
    pub predicates: PredicateRefs,
    pub cache: RefCell<Option<(Vec<u8>, u64)>>,
}

<Register> node: raw byte-array access to a register block.

The base register type — an address, a byte count, and no interpretation of the bytes. StringNode is this plus UTF-8/NUL decoding.

Fields

name: String

Unique feature name.

meta: NodeMeta

Shared metadata (visibility, description, tooltip, etc.).

addressing: Addressing

Register addressing metadata, including the block length.

access: AccessMode

Declared access rights.

port: Option<String>

<pPort> target; None or "Device" means the device port.

Any other port is parsed and listed but cannot be read — see GA-12.

predicates: PredicateRefs

Predicate refs gating implementation / availability / lock state.

cache: RefCell<Option<(Vec<u8>, u64)>>

Cached payload alongside the generation it was read in.

Implementations

impl RegisterNode

pub fn declared_len(&self) -> Option<u32>

Declared length of the register block in bytes.

None for a selector-mapped block, whose length depends on the current selector value and therefore needs a transport to resolve — use NodeMap::register_address for that.

This exists so a consumer can report a register’s size without naming Addressing, which is not re-exported (backlog API-02).

Trait Implementations

impl Debug for RegisterNode

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

Formats the value using the given formatter.
