Struct EitCollector 

pub struct EitCollector { /* private fields */ }

EIT-specific collector.

Present/following EITs complete as one normal section set. Schedule EITs complete only when every schedule table_id from the kind’s first table_id through the advertised last_table_id has completed its own section set.

Memory bounds

The collector is bounded by DEFAULT_MAX_LOGICAL_KEYS (configurable via with_max_logical_keys). When the sections or schedules map is full, incoming sections for new keys are skipped until space frees — the same skip-until-space policy as crate::carousel::ModuleReassembler.

Implementations

impl EitCollector

pub fn new() -> Self

Create an empty EIT collector with the default cap (DEFAULT_MAX_LOGICAL_KEYS).

pub fn with_max_logical_keys(self, max_logical_keys: usize) -> Self

Replace the logical-key cap (default DEFAULT_MAX_LOGICAL_KEYS). The cap is applied independently to the sections and schedules maps. Sections for new keys are skipped when the relevant map is full, until clear or retain_logical frees capacity.

pub fn push_section( &mut self, bytes: impl AsRef<[u8]>, ) -> CollectResult<Option<CompletedEit>>

Push one complete EIT section.

Returns Some for a completed present/following table or a completed schedule table-id range.

Errors

Returns a CollectError if the incoming section is malformed, inconsistent with already retained bytes, or not an EIT section. Treat the error as applying to this section only unless your application wants strict stream-fail behavior.

pub fn push_section_with_pid( &mut self, pid: Option<u16>, bytes: impl AsRef<[u8]>, ) -> CollectResult<Option<CompletedEit>>

Push one complete EIT section with PID context.

pub fn clear(&mut self)

Drop all retained EIT partial and completed schedule state.

Long-running receivers that collect EPG data continuously can call this at an application-defined carousel boundary if they do not need older schedule state.

pub fn retain_logical<F>(&mut self, keep: F)

where F: FnMut(&EitLogicalKey) -> bool,

Retain only logical EIT keys accepted by keep.

This is the explicit pruning hook for long-running EIT schedule collection. Both in-progress section sets and completed schedule ranges for rejected keys are removed.

pub fn section_set_len(&self) -> usize

Number of retained EIT section-set states.

pub fn schedule_len(&self) -> usize

Number of retained EIT logical schedule states.

Trait Implementations

impl Debug for EitCollector

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

Formats the value using the given formatter.

impl Default for EitCollector

fn default() -> Self

Returns the “default value” for a type.
