Struct ContextCheckpoint 

pub struct ContextCheckpoint {
    pub parent: Option<String>,
    pub covered_from: u64,
    pub covered_to: u64,
    pub covered_event_root: String,
    pub control: ControlFrame,
    pub artifact_refs: Vec<String>,
    pub narrative_observation: Option<String>,
}

A provider-neutral context checkpoint over a covered event range.

Fields

parent: Option<String>

covered_from: u64

covered_to: u64

covered_event_root: String

Chain head over the covered range.

control: ControlFrame

artifact_refs: Vec<String>

Content-addressed artifact references the projection keeps.

narrative_observation: Option<String>

Optional narrative summary, as a recorded-observation handle. It is untrusted and can never substitute for control-frame facts.

Implementations

impl ContextCheckpoint

pub fn validate_against( &self, live_accepted_root: &str, live_graph_revision: &str, live_authority_epoch: u64, ) -> Result<()>

Structural validation before use (PSP-9 system 14): range sanity, and equality of the live accepted root, revision, and epoch. A stale checkpoint is rebuilt, never patched by a model.

Trait Implementations

impl Clone for ContextCheckpoint

fn clone(&self) -> ContextCheckpoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContextCheckpoint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContextCheckpoint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContextCheckpoint

fn eq(&self, other: &ContextCheckpoint) -> 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 Serialize for ContextCheckpoint

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
