password-hash: extract CustomizedPasswordHasher trait#2105
Merged
Conversation
Splits out `PasswordHasher::hash_password_customized` into its own separate `CustomizedPasswordHasher` trait. This trait retains the associated `Params` type since that's used as a method argument. This also adds a type alias `Version` for `u32` to use in place of `Decimal` (also a `u32` alias) for the `Version` parameter to `hash_password_customized`, and changes the `salt` parameter to be `&'a str`, which removes any PHC-related types as input arguments to the method. However, there is still a dependency on `ParamsString` and `PasswordHash`, which still needs to be addressed to fully decouple the trait from PHC types.

## Added - Generic `H` param to traits to support multiple string formats e.g. PHC, MCF (#2110) - Implement `From<phc::Error>` for `Error` (#2124) - `rand_core` feature (#2126) - Salt generating helper functions `(try_)generate_salt` (#2128) - `Error::RngFailure` variant (#2337) ## Changed - Edition changed to 2024 and MSRV bumped to 1.85 (#1759) - Extract `CustomizedPasswordHasher` trait (#2105) - Bump `getrandom` to v0.4 (#2258) ## Removed - `Encoding` enum (#2102) - PHC types moved to the `phc` crate, which is re-exported as `password_hash::phc` when the `phc` crate feature is enabled (#2103, #2116): - `Ident` - `Output` - `ParamsString` - `PasswordHash` - `PasswordHashString` - `Salt` - `SaltString` - `Value` - `McfHasher` trait (#2334)
