Struct IPFixParser 

pub struct IPFixParser { /* private fields */ }

Stateful IPFIX parser with LRU template caches and optional pending flow support. Supports both native IPFIX templates and V9-style templates embedded in IPFIX messages.

Implementations

impl IPFixParser

pub fn validate_config(config: &Config) -> Result<(), ConfigError>

Validates a configuration without allocating parser internals.

pub fn try_new(config: Config) -> Result<Self, ConfigError>

Create a new IPFixParser with a custom template cache size and optional TTL configuration.

Arguments

• config - Configuration struct containing max_template_cache_size and optional ttl_config

Errors

Returns ConfigError if max_template_cache_size is 0

impl IPFixParser

pub fn available_template_ids(&self) -> Vec<u16>

Returns a sorted, deduplicated list of all available template IDs.

Trait Implementations

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

Formats the value using the given formatter.

impl Default for IPFixParser

fn default() -> Self

Returns the “default value” for a type.

impl ParserConfig for IPFixParser

fn set_pending_flows_config( &mut self, config: Option<PendingFlowsConfig>, ) -> Result<(), ConfigError>

fn set_ttl_config( &mut self, ttl_config: Option<TtlConfig>, ) -> Result<(), ConfigError>

Set the TTL configuration for templates

fn pending_flows_enabled(&self) -> bool

Returns whether pending flow caching is enabled.

fn pending_flow_count(&self) -> usize

Returns the total number of pending flow entries across all template IDs.

fn clear_pending_flows(&mut self)

Clear all pending flows, recording dropped metrics.
