Struct 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 entry in bytes.

Note that for non-delta entries this will be the size of the object itself.

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, ) -> Result<Entry, Error>

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: &mut dyn Read, pack_offset: Offset, hash_len: usize, ) -> Result<Entry>

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)

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Entry

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

impl PartialOrd for Entry

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Entry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Entry
