Struct SegmentTracker 

pub struct SegmentTracker { /* private fields */ }

A data structure to track received segments of a file.

This implementation uses a sorted, merged list of received ranges to efficiently track progress and identify missing data.

Implementations

impl SegmentTracker

pub fn new(file_size: u64) -> Self

Creates a new tracker for a file of a given size.

pub fn add_segment(&mut self, offset: u64, len: u64) -> Result<(), CfdpError>

Records that a segment of the file has been received. This method will merge overlapping or adjacent ranges to maintain a minimal list of disjoint received segments.

pub fn get_missing_ranges(&self) -> impl Iterator<Item = (u64, u64)> + '_

Returns a list of ranges (offset, length) that are still missing.

pub fn is_complete(&self) -> bool

Checks if the entire file has been received.

Trait Implementations

impl Clone for SegmentTracker

fn clone(&self) -> SegmentTracker

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SegmentTracker

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

Formats the value using the given formatter.
