⚠ rocket_flex_session breaking changes

--- failure derive_trait_impl_removed: built-in derived trait no longer implemented ---

Description:
A public type has stopped deriving one or more traits. This can break downstream code that depends on those types implementing those traits.
        ref: https://doc.rust-lang.org/reference/attributes/derive.html#derive
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/derive_trait_impl_removed.ron

Failed in:
  type RocketFlexSession no longer derives Clone, in /tmp/.tmpN2CvCj/rocket-flex-session/src/fairing.rs:58

--- failure enum_missing: pub enum removed or renamed ---

Description:
A publicly-visible enum cannot be imported by its prior path. A `pub use` may have been removed, or the enum itself may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/enum_missing.ron

Failed in:

  enum rocket_flex_session::storage::redis::RedisType, previously in file /tmp/.tmpl6hiLZ/rocket_flex_session/src/storage/redis.rs:12

--- failure inherent_method_missing: pub method removed or renamed ---

Description:
A publicly-visible method or associated fn is no longer available under its prior name. It may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/inherent_method_missing.ron

--- failure method_requires_different_generic_type_params: method now requires a different number of generic type parameters ---

Description:
A method now requires a different number of generic type parameters than it used to. Uses of this method that supplied the previous number of generic types will be broken.
        ref: https://doc.rust-lang.org/reference/items/generics.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/method_requires_different_generic_type_params.ron

Failed in:
  rocket_flex_session::Session::get_key takes 0 generic types instead of 1, in /tmp/.tmpN2CvCj/rocket-flex-session/src/session_hash.rs:33

--- failure module_missing: pub module removed or renamed ---

Description:
A publicly-visible module cannot be imported by its prior path. A `pub use` may have been removed, or the module may have been renamed, removed, or made non-public.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.43.0/src/lints/module_missing.ron
