Struct git_odb::data::Entry

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

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: u64

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

Implementations

impl Entry

Access

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

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

pub fn pack_offset(&self) -> u64

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()

impl Entry

Decoding

pub fn from_bytes(d: &[u8], pack_offset: u64) -> 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: u64) -> Result<Entry, Error>

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

Trait Implementations

impl Clone for Entry

pub 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

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

Formats the value using the given formatter.

impl Hash for Entry

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Entry

pub 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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Entry> for Entry

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Entry> for Entry

pub fn partial_cmp(&self, other: &Entry) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
