FileRef class final

One immutable file reference: the typed view of the contract's FileRefData — a wire-safe snapshot of one lp_file_refs row. Bytes live in the runtime's blob store; metadata lives in the kernel.

Constructors

FileRef({required String refId, required String store, required String recordId, required String field, required String hash, required String state, String? name, String? group, String? remoteName, int nextRetryAt = 0, int attemptCount = 0, String? lastError})

Creates a file reference.
