Struct SackBlocks Copy item path

impl SackBlocks

pub const EMPTY: Self

A constant empty instance of SACK blocks.

pub const MAX_BLOCKS: usize = 4usize

The maximum number of selective ack blocks that can be in a TCP segment.

See [RFC 2018 section 3].

[RFC 2018 section 3] https://www.rfc-editor.org/rfc/rfc2018#section-3

pub fn as_option(&self) -> Option<TcpOption<'_>>

Returns the contained selective ACKs as a TCP option.

Returns None if this SackBlocks is empty.

pub fn iter_skip_invalid(&self) -> impl Iterator<Item = SackBlock> + '_

Returns an iterator over the valid SackBlocks contained in this option.

pub fn try_iter( &self, ) -> impl Iterator<Item = Result<SackBlock, InvalidSackBlockError>> + '_

Returns an iterator yielding the results of converting the blocks in this option to valid SackBlocks.

pub fn from_option(blocks: &[TcpSackBlock]) -> Self

Creates a new SackBlocks option from a slice of blocks seen in a TCP segment.

Ignores any blocks past SackBlocks::MAX_BLOCKS.

pub fn is_empty(&self) -> bool

Returns true if there are no blocks present.

pub fn clear(&mut self)

Drops all blocks.
