Struct EnterpriseFieldRegistry 

pub struct EnterpriseFieldRegistry { /* private fields */ }

Registry for storing user-defined enterprise field definitions

This registry is used internally by parsers to look up custom field metadata during parsing.

Implementations

impl EnterpriseFieldRegistry

pub fn new() -> Self

Create a new empty registry

pub fn with_max_capacity(max: usize) -> Self

Create a new empty registry with a maximum capacity.

Once the limit is reached, further register calls that would insert new entries are silently ignored. Replacements of existing (enterprise_number, field_number) pairs are always allowed.

Panics

Panics if max is 0. A zero-capacity registry would silently drop every registration attempt.

pub fn register(&mut self, def: EnterpriseFieldDef) -> bool

Register a single enterprise field definition

If a field with the same enterprise number and field number already exists, it will be replaced. If a max_capacity is set and the registry is full, new (non-replacement) entries are dropped and false is returned.

pub fn register_many( &mut self, defs: impl IntoIterator<Item = EnterpriseFieldDef>, ) -> usize

Register multiple enterprise field definitions at once. Returns the number of definitions successfully registered.

pub fn get( &self, enterprise_number: u32, field_number: u16, ) -> Option<&EnterpriseFieldDef>

Look up a field definition by enterprise number and field number

pub fn contains(&self, enterprise_number: u32, field_number: u16) -> bool

Check if a field is registered

pub fn len(&self) -> usize

Get the number of registered fields

pub fn is_empty(&self) -> bool

Check if the registry is empty

pub fn clear(&mut self)

Clear all registered fields
