Variants

FromSource

Fields

path: FieldPath

WholeSource

AsCapture

Similar to WholeSource but with field-level transformations Used by #[capture] macro to apply transforms to specific fields in an account

FromContext

From instruction context (timestamp, slot, signature) Used by #[track_from] with special fields like __timestamp

Fields

field: String
