Expand description
Representation of an event in the Event Graph
Fields§
§timestamp: u64
Timestamp of the event in whole seconds
content: Vec<u8>
Content of the event
parents: [Hash; 5]
Parent nodes in the event DAG
layer: u64
DAG layer index of the event
Implementations§
Source§impl Event
impl Event
Sourcepub async fn new(data: Vec<u8>, event_graph: &EventGraph) -> Self
pub async fn new(data: Vec<u8>, event_graph: &EventGraph) -> Self
Create a new event with the given data and an EventGraph
reference.
The timestamp of the event will be the current time, and the parents
will be N_EVENT_PARENTS
from the current event graph unreferenced tips.
The parents can also include NULL, but this should be handled by the rest
of the codebase.
Sourcepub async fn with_timestamp(
timestamp: u64,
data: Vec<u8>,
event_graph: &EventGraph,
) -> Self
pub async fn with_timestamp( timestamp: u64, data: Vec<u8>, event_graph: &EventGraph, ) -> Self
Same as Event::new()
but allows specifying the timestamp explicitly.
Sourcepub async fn validate(
&self,
dag: &Tree,
genesis_timestamp: u64,
days_rotation: u64,
overlay: Option<&SledTreeOverlay>,
) -> Result<bool>
pub async fn validate( &self, dag: &Tree, genesis_timestamp: u64, days_rotation: u64, overlay: Option<&SledTreeOverlay>, ) -> Result<bool>
Fully validate an event for the correct layout against provided
DAG [sled::Tree
] reference and enforce relevant age, assuming
some possibility for a time drift. Optionally, provide an overlay
to use that instead of actual referenced DAG.
Sourcepub async fn dag_validate(&self, event_graph: &EventGraph) -> Result<bool>
pub async fn dag_validate(&self, event_graph: &EventGraph) -> Result<bool>
Fully validate an event for the correct layout against provided
EventGraph
reference and enforce relevant age, assuming some
possibility for a time drift.
Sourcepub fn validate_new(&self) -> bool
pub fn validate_new(&self) -> bool
Validate a new event for the correct layout and enforce relevant age, assuming some possibility for a time drift. Note: This validation does NOT check for recursive references(circles), and should be used as a first quick check.
