Struct ReferrerInfo 

pub struct ReferrerInfo {
    pub from_id: String,
    pub rel_types: Vec<String>,
    pub mem: String,
}

Typed payload for a single Write-Mem referrer in EngineError::HasIncomingRefs. Captures the (from_id, rel_types, mem) triple the surface envelope projects so consumers can reason about the offending edges without a follow-up memstead_entity call. The mem is always a Write-Mem — ReadOnly referrers are partitioned out before this struct is constructed and surfaced via the residual-stub warning channel instead.

Per-source deduplication: when one source entity has multiple edges of different rel-types pointing at the deletion target, the engine collapses them into a single ReferrerInfo whose rel_types list carries every edge type. A prior shape emitted one entry per edge, making a source-with-N-edges look like N distinct referrers in the error message and structured payload.

Fields

from_id: String

Trait Implementations

impl Clone for ReferrerInfo

fn clone(&self) -> ReferrerInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferrerInfo

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

Formats the value using the given formatter.

impl Display for ReferrerInfo

Inline rendering on the text mirror. Single rel-type renders as just the referring entity id; multiple rel-types append the ×N [REL1, REL2] annotation so the count and the offending edge-types stay visible without parsing the structured payload.

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

Formats the value using the given formatter.

impl Serialize for ReferrerInfo

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
