Struct git_odb::loose::Db [−][src]
pub struct Db { pub path: PathBuf, }
A database for reading and writing objects to disk, one file per object.
Fields
path: PathBuf
The directory in which objects are stored, containing 256 folders representing the hashes first byte.
Implementations
impl Db
[src]
impl Db
[src]Object lookup
pub fn contains(&self, id: impl AsRef<oid>) -> bool
[src]
pub fn contains(&self, id: impl AsRef<oid>) -> bool
[src]Returns true if the given id is contained in our repository.
pub fn find<'a>(
&self,
id: impl AsRef<oid>,
out: &'a mut Vec<u8>
) -> Result<Option<Object<'a>>, Error>
[src]
pub fn find<'a>(
&self,
id: impl AsRef<oid>,
out: &'a mut Vec<u8>
) -> Result<Option<Object<'a>>, Error>
[src]Return the object identified by the given ObjectId
if present in this database,
writing its raw data into the given out
buffer.
Returns Err
if there was an error locating or reading the object. Returns Ok<None>
if
there was no such object.
impl Db
[src]
impl Db
[src]Iteration and traversal
pub fn iter(&self) -> Type
[src]
pub fn iter(&self) -> Type
[src]Return an iterator over all objects contained in the database.
The Id
s returned by the iterator can typically be used in the locate(…)
method.
Note that the result is not sorted or stable, thus ordering can change between runs.
Notes
IterType
is used instead of impl Iterator<…>
to allow using this iterator in struct fields, as is currently
needed if iterators need to be implemented by hand in the absence of generators.
Trait Implementations
impl Write for Db
[src]
impl Write for Db
[src]fn write_buf(
&self,
kind: Kind,
from: &[u8],
hash: Kind
) -> Result<ObjectId, Self::Error>
[src]
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.
