Available on crate feature streaming-input only.

An item of the iteration produced by BytesToEntriesIter

Fields

header: Header

The header of a pack entry

header_size: u16

The amount of bytes used to encode the header. pack_offset + header_size is the beginning of the compressed data in the pack.

pack_offset: u64

The first byte of the entry at which the header can be read.

compressed: Option<Vec<u8>>

The bytes consumed while producing decompressed These do not contain the header, which makes it possible to easily replace a RefDelta with offset deltas when resolving thin packs. Depends on CompressionMode when the iterator is initialized.

compressed_size: u64

The amount of bytes the compressed portion of the entry takes, i.e. the portion behind behind the header.

crc32: Option<u32>

The CRC32 over the complete entry, that is encoded header and compressed object data. Depends on CompressionMode when the iterator is initialized

decompressed_size: u64

The amount of decompressed bytes of the entry.

trailer: Option<ObjectId>

Set for the last object in the iteration, providing the hash over all bytes of the iteration for use as trailer in a pack or to verify it matches the trailer.

Implementations

impl Entry

pub fn from_data_obj(obj: &Data<'_>, pack_offset: u64) -> Result<Self, Error>

Create a new input entry from a given data obj set to be placed at the given pack_offset.

This method is useful when arbitrary base entries are created

pub fn bytes_in_pack(&self) -> u64

The amount of bytes this entry may consume in a pack data file

pub fn compute_crc32(&self) -> u32

Update our CRC value by recalculating it from our header and compressed data.

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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Entry

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

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

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

This method 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

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.

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

impl StructuralPartialEq for Entry
