Struct RootEvent 

pub struct RootEvent {
    pub kind: RootKind,
    pub content: RawContentId,
    pub seq: u64,
}

A specific rooting event, addressed by its own content.

Why seq

An operator can type “run the tests” twice in one session. Those are two turns, and a unit rooted in the second must not be indistinguishable from one rooted in the first. Content alone collapses them; seq is what keeps “which turn” answerable. It is the session-local ordinal of the event, so it is deterministic — a replay of the same session mints the same ids.

Fields

kind: RootKind

What kind of event this was.

content: RawContentId

The event’s own material — the prompt bytes, the action record, the harness event record. A RawContentId because this is an opaque byte string, not a canonical structured value.

seq: u64

Session-local ordinal, so two identical events remain distinct.

Implementations

impl RootEvent

pub fn new(kind: RootKind, material: &[u8], seq: u64) -> Self

Address a rooting event by hashing its material.

pub fn id(&self) -> Result<ContentId, ContentError>

This event’s address — what a crate::Unit references.

Errors

Propagates an encoding failure from the canonical form.

Trait Implementations

impl Clone for RootEvent

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContentAddressable for RootEvent

fn canonical_form(&self) -> Result<Vec<u8>, ContentError>

Produce the deterministic byte representation of this value.

fn content_id(&self) -> Result<ContentId, ContentError>

Compute this value’s ContentId.

fn verify(&self, expected: &ContentId) -> Result<bool, ContentError>

Check whether this value’s content id matches an expected id.

fn ensure_content_id(&self, expected: &ContentId) -> Result<(), ContentError>

Verify, returning an error on mismatch instead of Ok(false).

fn from_canonical_form(bytes: &[u8]) -> Result<Self, ContentError>

where Self: Sized + DeserializeOwned,

Checked ingress: decode a value from its canonical form, proving the bytes reproduce it — a checked partial inverse of canonical_form.

impl Copy for RootEvent

impl Debug for RootEvent
