Struct AliasRegistry 

pub struct AliasRegistry { /* private fields */ }

Bidirectional name↔alias bindings plus a datatype index, scoped to one Edge Node or Device.

Implementations

impl AliasRegistry

pub fn new() -> Self

An empty registry.

pub fn bind(&mut self, name: &str, alias: Option<u64>, datatype: DataType)

Bind a metric’s name (and optional alias) to its datatype, as declared in a BIRTH. Overwrites any existing binding for the same name/alias; use AliasRegistry::try_bind to enforce the duplicate-alias-is-fatal rule.

pub fn try_bind( &mut self, name: &str, alias: Option<u64>, datatype: DataType, ) -> Result<()>

Like AliasRegistry::bind, but rejects an alias already bound to a different name — a duplicate alias in a BIRTH is fatal per the spec.

Errors

Returns SparkplugError::InvalidId if alias is already bound to a different metric name.

pub fn datatype_for_name(&self, name: &str) -> Option<DataType>

The datatype declared for name, if any.

pub fn datatype_for_alias(&self, alias: u64) -> Option<DataType>

The datatype declared for alias, if any.

pub fn datatype_for(&self, key: &MetricKey) -> Option<DataType>

The datatype for a MetricKey.

pub fn name_for_alias(&self, alias: u64) -> Option<&str>

The name bound to alias, if any.

pub fn alias_for_name(&self, name: &str) -> Option<u64>

The alias bound to name, if any.

pub fn alias_exists(&self, alias: u64) -> bool

Whether alias is already bound (to detect duplicate aliases in a birth).

pub fn clear(&mut self)

Clear every binding (call before re-binding on a new birth).
