    fn write_stream(
        &self, 
        kind: Kind, 
        size: u64, 
        from: impl Read,

}

Describe the capability to write git objects into an object store.

Associated Types

type Error: Error + From<Error>[src]

The error type used for all trait methods.

Note the default implementations require the From<io::Error> bound.

Required methods

fn write_stream(
    &self,
    kind: Kind,
    size: u64,
    from: impl Read,
    hash: Kind
) -> Result<ObjectId, Self::Error>[src]

As write, but takes an input stream. This is commonly used for writing blobs directly without reading them to memory first.

Provided methods

fn write(&self, object: &Object, hash: Kind) -> Result<ObjectId, Self::Error>[src]

Write object using the given kind of hash into the database, returning id to reference it in subsequent reads.

fn write_buf(
    &self,
    object: Kind,
    from: &[u8],
    hash: Kind
) -> Result<ObjectId, Self::Error>[src]

As write, but takes an object kind along with its encoded bytes.

Implementors

impl Write for git_odb::compound::Db[src]

type Error = Error

impl Write for git_odb::linked::Db[src]

type Error = Error

impl Write for git_odb::loose::Db[src]

type Error = Error

fn write_buf(
    &self,
    kind: Kind,
    from: &[u8],
    hash: Kind
) -> Result<ObjectId, Self::Error>[src]

Write the given buffer in from to disk in one syscall at best.

This will cost at least 4 IO operations.

fn write_stream(
    &self,
    kind: Kind,
    size: u64,
    from: impl Read,
    hash: Kind
) -> Result<ObjectId, Self::Error>[src]

Write the given stream in from to disk with at least one syscall.

This will cost at least 4 IO operations.
