General-purpose lints

Use of dylint_linting’s constituent feature

The general-purpose lints use dylint_linting’s constituent feature. This allows the lints to be built in either of the following two configurations:

• as individual libraries
• as a single, combined general library

However, some additional organization of both the general directory and its subdirectories is required.

For the general directory itself:

• Each lint is listed under [dependencies] in general/Cargo.toml
• Each lint is listed under [workspace.members] in general/Cargo.toml
• Each lint’s register_lints function is called from the register_lints function in src/lib.rs.

For each lint subdirectory:

• The following files do not appear, even though they would be created by cargo dylint new:
  • .cargo/config.toml
  • .gitignore
  • rust-toolchain
• The lint’s Cargo.toml has the following [lib] section (note: crate-type is not just ["cdylib"]):

  [lib]
  crate-type = ["cdylib", "rlib"]
  

• The lint gets its clippy_utils dependency from the workspace, i.e.:

  [dependencies]
  clippy_utils = { workspace = true }
  

• The lint’s Cargo.toml has the following [features] section:

  [features]
  rlib = ["dylint_linting/constituent"]
