Currently, only structs can be marked as #[deprecated] and the warning for using deprecated structs will not be emitted for all expressions in which a struct can be used.

Since we do not emit any error or warning for using #[deprecated] aside of stucts, this leads to a misleading usage, where items are annotated as #[depricated] but that annotation does not have any effect.

E.g., some examples of using #[deprecated] without any effect in the standard library:

  • std::constants::ZERO_B256
  • std::ecr::ec_recover
  • std::evm::ecr::ec_recover_evm_address

Warning for usages of #[deprecated] outside of struct declarations will be done in #6880.

This issues calls for step-wise implementation of #[deprecated] in two directions:

  • allowing it on all items where it makes sense.
  • checking for usages of deprecated items in all places.

Extend #[deprecated] support
1ece71a 
Add support for the `#[deprecated]` attribute to functions, enums,
struct items, enum variants and propagate deprecation check exhaustively
throughout expressions variants.

Partially addresses #6942.

Support for deprecating traits, abis and the methods thereof in their
definitions is still missing, as well as scrutinees and storage fields.
