Attribute Macro frame_support::pallet_macros::call_index

#[call_index]

Enforce the index of a variant in the generated enum Call.

See call for more information.

All call indexes start from 0, until it encounters a dispatchable function with a defined call index. The dispatchable function that lexically follows the function with a defined call index will have that call index, but incremented by 1, e.g. if there are 3 dispatchable functions fn foo, fn bar and fn qux in that order, and only fn bar has a call index of 10, then fn qux will have an index of 11, instead of 1. Each dispatchable may also be annotated with the #[pallet::call_index($idx)] attribute, which explicitly defines the codec index for the dispatchable function in the Call enum.
