Struct tinychain::txn::Txn [−][src]
A transaction context.
Implementations
impl Txn[src]
pub fn ref_count(&self) -> usize[src]
Return the current number of strong references to this Txn.
pub async fn claim(
self,
actor: &Actor,
cluster_path: TCPathBuf
) -> TCResult<Self>[src]
self,
actor: &Actor,
cluster_path: TCPathBuf
) -> TCResult<Self>
Claim ownership of this transaction.
pub async fn grant(
&self,
actor: &Actor,
cluster_path: TCPathBuf,
scopes: Vec<Scope>
) -> TCResult<Self>[src]
&self,
actor: &Actor,
cluster_path: TCPathBuf,
scopes: Vec<Scope>
) -> TCResult<Self>
pub fn is_owner(&self, cluster_path: &[PathSegment]) -> bool[src]
Check if the cluster at the specified path on this host is the owner of the transaction.
pub fn owner(&self) -> Option<&Link>[src]
Return the owner of this transaction, if there is one.
pub fn link(&self, path: TCPathBuf) -> Link[src]
Return a link to the given path on this host.
pub fn request(&self) -> &Request[src]
Return the Request which initiated this transaction on this host.
pub async fn get(&self, link: Link, key: Value) -> TCResult<State>[src]
Resolve a GET op within this transaction context.
pub async fn put(&self, link: Link, key: Value, value: State) -> TCResult<()>[src]
Resolve a PUT op within this transaction context.
pub async fn post(&self, link: Link, params: State) -> TCResult<State>[src]
Resolve a POST op within this transaction context.
pub async fn delete(&self, link: Link, key: Value) -> TCResult<()>[src]
Resolve a DELETE op within this transaction context.
