Struct den::SegmentRef

source ·
pub struct SegmentRef {
    pub start: usize,
    pub block_count: usize,
}
Expand description

One or more successive blocks found in the common data.

Fields§

§start: usize

Start of segment with a length of Self::block_count*Signature::block_size.

§block_count: usize

The number of blocks this segment references.

Implementations§

source§

impl SegmentRef

source

pub fn start(self) -> usize

The start in the base resource this reference is pointing to.

source

pub fn block_count(self) -> usize

The number of blocks this reference covers.

source

pub fn len(self, block_size: usize) -> usize

The length of the referred data.

source

pub fn end(self, block_size: usize) -> usize

The end of this segment.

The same as Self::start + Self::block_count * block_size.

source

pub fn len_to_end( self, diff: &Difference<impl ExtendVec + 'static> ) -> Option<usize>

Get the length to the end of diff. If this Segment::Ref doesn’t reach diff’s end, None is returned. Else, the count of bytes until the end of copying is returned.

source

pub fn with_start(self, start: usize) -> Self

Get a new SegmentRef with Self::start set to start.

source

pub fn with_blocks(self, n: usize) -> Self

Get a new SegmentRef with Self::block_count set to n.

source

pub fn extend(&mut self, n: usize)

source

pub fn multiply(&mut self, n: usize)

Multiplies the count of blocks. Can be useful if the block size changes.

impl PartialEq for SegmentRef

source§

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