Enum libjp::Change

pub enum Change {
    NewNode {
        id: NodeId,

    },

A single change.

Variants

NewNode

A change which adds a new node to the graggle, with an ID that must be unique, and with the given contents.

Fields of NewNode

id: NodeId

The ID of the new node.

contents: Vec<u8>

The contents of the new node.

DeleteNode

Marks a node as deleted. Note that deleted nodes are never actually removed; they remain but they are simply marked as deleted.

Fields of DeleteNode

id: NodeId

The ID of the node to delete.

NewEdge

Adds a new edge (i.e. a new ordering relation) between two nodes. Those nodes must either already exist in the graggle at the time this change is applied. (If this Change is part of a Changes that adds some nodes and also an edge between them, then that's ok too.)

Fields of NewEdge

src: NodeId

The source of the new edge (i.e. the one that comes first in the ordering).

dest: NodeId

The destination of the new edge.

Trait Implementations

impl Clone for Change

fn clone(&self) -> Change

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for Change

impl PartialEq<Change> for Change

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for Change

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Change

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, 

Feeds a slice of this type into the given [Hasher].

impl<'de> Deserialize<'de> for Change

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
