Implementations

impl LocalChange<Local>

pub fn knows(&self, hash: &Hash) -> bool

pub fn has_edge(
    &self,
    hash: Hash,
    from: Position<Option<Hash>>,
    to: Position<Option<Hash>>,
    flags: EdgeFlags
) -> bool

impl LocalChange<Local>

pub fn inverse(
    &self,
    hash: &Hash,
    header: ChangeHeader,
    metadata: Vec<u8>
) -> Self

impl<L> LocalChange<L>

pub fn make_change<T: TxnT>(
    txn: &T,
    channel: &ChannelRef<T>,
    changes: Vec<Record<Option<Hash>, L>>,
    contents: Vec<u8>,
    header: ChangeHeader,
    metadata: Vec<u8>
) -> Self

pub fn new() -> Self

impl LocalChange<Local>

pub fn size_no_contents<R: Read + Seek>(r: &mut R) -> Result<u64, Error>

pub fn serialize<W: Write>(&self, w: W) -> Result<Hash, Error>

Serialise the change as a file named ".change" in directory dir, where "" is the actual hash of the change.

pub fn check_from_buffer(buf: &[u8], hash: &Hash) -> Result<(), Error>

Deserialise a change from the file given as input file.

pub fn deserialize(file: &str, hash: Option<&Hash>) -> Result<Self, Error>

Deserialise a change from the file given as input file.

pub fn hash(&self) -> Result<Hash, Error>

Compute the hash of this change. If the zstd feature is enabled, it is probably more efficient to serialise the change (using the serialize method) at the same time, which also returns the hash.

impl LocalChange<Local>

pub fn write_all_deps<F: FnMut(Hash) -> Result<(), Error>>(
    &self,
    f: F
) -> Result<(), Error>

pub fn write<W: Write, C: ChangeStore, F: FnMut(&Local, Position<Option<Hash>>) -> String>(
    &self,
    changes: &C,
    hash: Option<Hash>,
    file_name: F,
    write_header: bool,
    w: W
) -> Result<(), Error>

    r: R,
    updatables: &mut HashMap<usize, InodeUpdate>,
    txn: &T,
    channel: &ChannelRef<T>
) -> Result<Self, Error>

pub fn read<R: BufRead>(
    r: R,
    updatables: &mut HashMap<usize, InodeUpdate>
) -> Result<Self, Error>
