Struct MustReach 

pub struct MustReach {
    pub relationships: Vec<String>,
    pub direction: ReachDirection,
    pub terminal_types: Vec<String>,
    pub max_depth: Option<u32>,
    pub severity: ConstraintSeverity,
}

One reachability obligation on a type definition. The obligated entity must reach at least one non-stub entity whose type is in terminal_types, walking edges whose rel-type is in relationships (an inline relation set), in direction, within max_depth hops when bounded. Evaluated on the health sweep only (constraints axis), never on the write path — no single write completes a transitive absence. The incoming direction with max_depth: 1 covers the required-incoming-edge case.

Fields

relationships: Vec<String>

Edge names the walk follows — any name in the set continues the path. Loader validates each against the schema’s relationship vocabulary.

direction: ReachDirection

out follows edges pointing away from the walked entity, in follows edges pointing at it — the same vocabulary the store and memstead_search speak.

terminal_types: Vec<String>

Type names that satisfy the obligation when reached. Loader validates each against the schema’s declared types.

max_depth: Option<u32>

Maximum number of hops a conforming path may take. Absent = unbounded. Zero refuses at load (nothing is reachable in zero hops).

severity: ConstraintSeverity

Always warn — the loader refuses block on this form.

Trait Implementations

impl Clone for MustReach

fn clone(&self) -> MustReach

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MustReach

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MustReach

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for MustReach

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

Inequality operator !=.
