This trait provides a conversion to a convenience type FlatOp for use in the validation call back.

Not all data is available in the FlatOp. This is why the Op is not taken by value and can still be used after this conversion.

There is data that is common to all ops and can be accessed via helpers on the op.

• Get the Op::author() of the op.
• Get the Op::timestamp() for when the op was created.
• Get the Op::action_seq() of the op.
• Get the Op::prev_action() of the op.
• Get the Op::action_type() of the op.

Required Methods

fn flattened<ET, LT>(&self) -> Result<FlatOp<ET, LT>, WasmError>

where ET: EntryTypesHelper + UnitEnum, <ET as UnitEnum>::Unit: Into<ZomeTypesKey<EntryDefIndex>>, LT: LinkTypesHelper, WasmError: From<<ET as EntryTypesHelper>::Error> + From<<LT as LinkTypesHelper>::Error>,

Converts an Op to a FlatOp without consuming it. This will clone the required internal data.

Provided Methods

fn to_type<ET, LT>(&self) -> Result<FlatOp<ET, LT>, WasmError>

where ET: EntryTypesHelper + UnitEnum, <ET as UnitEnum>::Unit: Into<ZomeTypesKey<EntryDefIndex>>, LT: LinkTypesHelper, WasmError: From<<ET as EntryTypesHelper>::Error> + From<<LT as LinkTypesHelper>::Error>,

👎Deprecated: to_type has been renamed to flattened, please use that name instead

Alias for flattened, for backward compatibility
