Crate cw22

CW22 defines a way for a contract to declare which interfaces do the contract implement This standard is inspired by the EIP-165 from Ethereum. Originally it was proposed to be merged into CW2: Contract Info, then it is splitted to a separated cargo to keep CW2 being backward compatible. Each supported interface contains a string value pointing to the corresponding cargo package and a specific release of the package. There is also a function to check whether the contract support a specific version of an interface or not. The version string for each interface follows Semantic Versioning standard. More info is in: https://docs.rs/semver/latest/semver/

Structs

• query_supported_interface_version
• require_version
  query_supported_interface show if contract supports an interface with version following SemVer query query example“>=1.2.3, <1.8.0“
• set_contract_supported_interface
  set_contract_supported_interface should be used in instantiate to store the original version of supported interfaces. It should also be used after every migration.
