Struct SackBlock 

pub struct SackBlock {
    pub left_edge: u32,
    pub right_edge: u32,
}

A single SACK block representing a contiguous range of received bytes.

left_edge is the first sequence number in the block (inclusive). right_edge is one past the last sequence number (exclusive).

Fields

left_edge: u32

right_edge: u32

Implementations

impl SackBlock

pub const fn new(left_edge: u32, right_edge: u32) -> Self

Create a new SACK block.

pub fn contains(&self, seq: u32) -> bool

Returns true if this block contains the given sequence number.

pub fn len(&self) -> u32

Returns the length of this block in sequence space.

pub fn is_empty(&self) -> bool

Returns true if the block is empty (zero length).

pub fn overlaps_or_adjacent(&self, other: &SackBlock) -> bool

Returns true if this block overlaps or is adjacent to other.

pub fn merge(&mut self, other: &SackBlock)

Merge another block into this one (union of ranges). Only valid if the blocks overlap or are adjacent.

Trait Implementations

impl Clone for SackBlock

fn clone(&self) -> SackBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SackBlock

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

Formats the value using the given formatter.

impl PartialEq for SackBlock

fn eq(&self, other: &SackBlock) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
