Struct git2::Transaction [−][src]
pub struct Transaction<'repo> { /* fields omitted */ }Expand description
A structure representing a transactional update of a repository’s references.
Transactions work by locking loose refs for as long as the Transaction
is held, and committing all changes to disk when Transaction::commit is
called. Note that comitting is not atomic: if an operation fails, the
transaction aborts, but previous successful operations are not rolled back.
Implementations
impl<'repo> Transaction<'repo>[src]
impl<'repo> Transaction<'repo>[src]pub fn lock_ref(&mut self, refname: &str) -> Result<(), Error>[src]
pub fn lock_ref(&mut self, refname: &str) -> Result<(), Error>[src]Lock the specified reference by name.
pub fn set_target(
&mut self,
refname: &str,
target: Oid,
reflog_signature: Option<&Signature<'_>>,
reflog_message: &str
) -> Result<(), Error>[src]
pub fn set_target(
&mut self,
refname: &str,
target: Oid,
reflog_signature: Option<&Signature<'_>>,
reflog_message: &str
) -> Result<(), Error>[src]Set the target of the specified reference.
The reference must have been locked via lock_ref.
If reflog_signature is None, the Signature is read from the
repository config.
pub fn set_symbolic_target(
&mut self,
refname: &str,
target: &str,
reflog_signature: Option<&Signature<'_>>,
reflog_message: &str
) -> Result<(), Error>[src]
pub fn set_symbolic_target(
&mut self,
refname: &str,
target: &str,
reflog_signature: Option<&Signature<'_>>,
reflog_message: &str
) -> Result<(), Error>[src]Set the target of the specified symbolic reference.
The reference must have been locked via lock_ref.
If reflog_signature is None, the Signature is read from the
repository config.
pub fn set_reflog(&mut self, refname: &str, reflog: Reflog) -> Result<(), Error>[src]
pub fn set_reflog(&mut self, refname: &str, reflog: Reflog) -> Result<(), Error>[src]Add a Reflog to the transaction.
This commit the in-memory Reflog to disk when the transaction commits.
Note that atomicty is *not guaranteed: if the transaction fails to
modify refname, the reflog may still have been comitted to disk.
If this is combined with setting the target, that update won’t be
written to the log (ie. the reflog_signature and reflog_message
parameters will be ignored).
