Struct Fact

pub struct Fact {
    pub fact_type_id: Field,
    pub payload: EphemeralArray<Field>,
    pub origin_block: Option<OriginBlock>,
}

A single immutable fact in a collection.

Fields

fact_type_id: Field

A user-defined identifier for fact kinds. Typically used to determine how to deserialize payload.

payload: EphemeralArray<Field>

origin_block: Option<OriginBlock>

The block the fact is associated to, if any. A fact with an origin block is said to be a 'retractable' fact, and will be automatically deleted if its origin block gets pruned in a reorg. Typically used by facts associated with a transaction (e.g. 'processed entry X using data from tx Y in block Z').
