Struct Traversal 

pub struct Traversal {
    pub depth: u32,
    pub as_of: Option<TimestampMs>,
    pub as_at: Option<TimestampMs>,
    pub group_id: Option<String>,
    pub max_nodes: usize,
}

Parameters for Grit::traverse. Default gives depth 3 (the AGENTS.md default bound), both timelines evaluated “now”, no group filter.

Fields

depth: u32

Maximum hops from the seed set (inclusive bound; default 3).

as_of: Option<TimestampMs>

Event-time instant: only walk edges whose [valid_at, invalid_at) interval contains this. None = clock now.

as_at: Option<TimestampMs>

System-time instant (“what did I believe at t?”): only walk edges whose [created_at, expired_at) interval contains this. None = clock now.

group_id: Option<String>

Restrict the walk to one namespace.

max_nodes: usize

Node budget: the walk halts (breadth-first, nearest wins) once this many nodes are reached. Keeps traversal latency independent of neighborhood size — Layer 3 asks for “context that fits”, never the 7,000-node ball around a hub. Default 256.

Implementations

impl Traversal

pub fn depth(self, depth: u32) -> Self

Set the hop bound.

pub fn as_of(self, t: TimestampMs) -> Self

Set the event-time instant.

pub fn as_at(self, t: TimestampMs) -> Self

Set the system-time (belief) instant — this is the time-travel knob.

pub fn group(self, group_id: impl Into<String>) -> Self

Restrict to a namespace.

pub fn max_nodes(self, n: usize) -> Self

Set the node budget (usize::MAX for an unbounded walk).

Trait Implementations

impl Clone for Traversal

fn clone(&self) -> Traversal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Traversal

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

Formats the value using the given formatter.

impl Default for Traversal

fn default() -> Self

Returns the “default value” for a type.
