Introspection
This crate handles type introspection of contracts. In other words, it examines which functions can be called on a given contract. This is referred to as the contract's interface.
Interfaces
Starting from version 3.x.x, the interfaces are no longer part of the openzeppelin_access package. The references
documented here are contained in the openzeppelin_interfaces package version 2.1.0-alpha.0.
use openzeppelin_interfaces::introspection::ISRC5;Interface of the SRC5 Introspection Standard as defined in SNIP-5.
