Struct git_pack::data::Entry

pub struct Entry {
    pub header: Header,
    pub decompressed_size: u64,
    pub data_offset: Offset,
}

An representing an full- or delta-object within a pack

Fields

header: Header

The entry’s header

decompressed_size: u64

The decompressed size of the object in bytes

data_offset: Offset

absolute offset to compressed object data in the pack, just behind the entry’s header

Implementations

impl Entry

Decoding

pub fn from_bytes(d: &[u8], pack_offset: Offset, hash_len: usize) -> Entry

Decode an entry from the given entry data d, providing the pack_offset to allow tracking the start of the entry data section.

Panics

If we cannot understand the header, garbage data is likely to trigger this.

pub fn from_read(
    r: impl Read,
    pack_offset: Offset,
    hash_len: usize
) -> Result<Entry, Error>

Instantiate an Entry from the reader r, providing the pack_offset to allow tracking the start of the entry data section.

impl Entry

Access

pub fn base_pack_offset(&self, distance: u64) -> Offset

Compute the pack offset to the base entry of the object represented by this entry.

pub fn pack_offset(&self) -> Offset

The pack offset at which this entry starts

pub fn header_size(&self) -> usize

The amount of bytes used to describe this entry in the pack. The header starts at Self::pack_offset()

Trait Implementations

impl Clone for Entry

fn clone(&self) -> Entry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Entry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Entry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Hash for Entry

fn hash<__H: Hasher>(&self, state: &mut __H)

impl Ord for Entry

fn cmp(&self, other: &Entry) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self
