Struct Operation 

pub struct Operation { /* private fields */ }

A wrapper around op_store::Operation that defines additional methods and stores a pointer to the OpStore the operation belongs to.

Implementations

impl Operation

pub fn new( op_store: Arc<dyn OpStore>, id: OperationId, data: impl Into<Arc<Operation>>, ) -> Self

pub fn op_store(&self) -> Arc<dyn OpStore>

pub fn id(&self) -> &OperationId

pub fn view_id(&self) -> &ViewId

pub fn parent_ids(&self) -> &[OperationId]

pub fn parents(&self) -> impl ExactSizeIterator<Item = OpStoreResult<Self>>

pub fn view(&self) -> OpStoreResult<View>

pub fn metadata(&self) -> &OperationMetadata

pub fn stores_commit_predecessors(&self) -> bool

Returns true if predecessors are recorded in this operation.

This returns false only if the operation was written by jj < 0.30.

pub fn predecessors_for_commit( &self, commit_id: &CommitId, ) -> Option<&[CommitId]>

Returns predecessors of the specified commit if recorded.

pub fn all_referenced_commit_ids(&self) -> impl Iterator<Item = &CommitId>

Iterates all commit ids referenced by this operation ignoring the view.

Use this in addition to View::all_referenced_commit_ids() to build commit index from scratch. The predecessor commit ids are also included, which ensures that the old commits to be returned by Self::predecessors_for_commit() are still reachable.

The iteration order is unspecified.

pub fn store_operation(&self) -> &Operation

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Operation

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Operation

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Operation

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Operation

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Operation

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Operation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
