Struct git_odb::pack::File

pub struct File { /* fields omitted */ }

Implementations

impl File

Reading of objects

pub fn decompress_entry(
    &self,
    entry: &Entry,
    out: &mut [u8]
) -> Result<usize, Error>

pub fn decode_entry(
    &self,
    entry: Entry,
    out: &mut Vec<u8>,
    resolve: impl Fn(&Id, &mut Vec<u8>) -> Option<ResolvedBase>,
    cache: &mut impl DecodeEntry
) -> Result<DecodeEntryResult, Error>

Decode an entry, resolving delta's as needed, while growing the output vector if there is not enough space to hold the result object. Returns (object_kind, compressed_size), referring to the entry in-pack size for use with CRC32 checks such as in crc32(pack_data[entry.data_offset..entry.data_offset + compressed_size])

impl File

Instantiation and basic file information

pub fn kind(&self) -> Kind

pub fn num_objects(&self) -> u32

pub fn data_len(&self) -> usize

pub fn path(&self) -> &Path

pub fn checksum(&self) -> Id

pub fn verify_checksum(&self) -> Result<Id, ChecksumError>

pub fn entry_crc32(&self, pack_offset: u64, size: usize) -> u32

Currently only done during pack verification - finding the right size is only possible by decompressing the pack entry beforehand, or by using the (to be sorted) offsets stored in an index file.

pub fn entry(&self, offset: u64) -> Entry

pub fn at(path: impl AsRef<Path>) -> Result<File, Error>

Trait Implementations

impl<'_> TryFrom<&'_ Path> for File

type Error = Error

The type returned in the event of a conversion error.

fn try_from(path: &Path) -> Result<Self, Self::Error>

Performs the conversion.
