### arithmetic-side-effects-allowed
|
||||
Suppress checking of the passed type names in all types of operations.
|
||||
|
||||
If a specific operation is desired, consider using `arithmetic_side_effects_allowed_binary` or `arithmetic_side_effects_allowed_unary` instead.
|
||||
|
||||
#### Example
|
||||
|
||||
```toml
|
||||
arithmetic-side-effects-allowed = ["SomeType", "AnotherType"]
|
||||
```
|
||||
|
||||
#### Noteworthy
|
||||
|
||||
A type, say `SomeType`, listed in this configuration has the same behavior of
|
||||
`["SomeType" , "*"], ["*", "SomeType"]` in `arithmetic_side_effects_allowed_binary`.
|
||||
|
||||
**Default Value:** `{}` (`rustc_data_structures::fx::FxHashSet<String>`)
|
||||
|
||||
* [arithmetic_side_effects](https://rust-lang.github.io/rust-clippy/master/index.html#arithmetic_side_effects)
|
||||
|
||||
|
||||
### arithmetic-side-effects-allowed-binary
|
||||
Suppress checking of the passed type pair names in binary operations like addition or
|
||||
multiplication.
|
||||
|
||||
Supports the "*" wildcard to indicate that a certain type won't trigger the lint regardless
|
||||
of the involved counterpart. For example, `["SomeType", "*"]` or `["*", "AnotherType"]`.
|
||||
|
||||
Pairs are asymmetric, which means that `["SomeType", "AnotherType"]` is not the same as
|
||||
`["AnotherType", "SomeType"]`.
|
||||
|
||||
#### Example
|
||||
|
||||
```toml
|
||||
arithmetic-side-effects-allowed-binary = [["SomeType" , "f32"], ["AnotherType", "*"]]
|
||||
```
|
||||
|
||||
**Default Value:** `[]` (`Vec<[String; 2]>`)
|
||||
|
||||
* [arithmetic_side_effects](https://rust-lang.github.io/rust-clippy/master/index.html#arithmetic_side_effects)
|
||||
|
||||
|
||||
### arithmetic-side-effects-allowed-unary
|
||||
Suppress checking of the passed type names in unary operations like "negation" (`-`).
|
||||
|
||||
#### Example
|
||||
|
||||
```toml
|
||||
arithmetic-side-effects-allowed-unary = ["SomeType", "AnotherType"]
|
||||
```
|
||||
|
||||
**Default Value:** `{}` (`rustc_data_structures::fx::FxHashSet<String>`)
|
||||
|
||||
* [arithmetic_side_effects](https://rust-lang.github.io/rust-clippy/master/index.html#arithmetic_side_effects)
|
||||
|
||||
|
||||
### avoid-breaking-exported-api
|
||||
Suppress lints whenever the suggested change would cause breakage for other crates.
|
||||
|
||||
**Default Value:** `true` (`bool`)

The list of words this lint should not consider as identifiers needing ticks. The value
|
||||
`".."` can be used as part of the list to indicate, that the configured values should be appended to the
|
||||
default configuration of Clippy. By default any configuraction will replace the default value. For example:
|
||||
* `doc-valid-idents = ["ClipPy"]` would replace the default list with `["ClipPy"]`.
|
||||
* `doc-valid-idents = ["ClipPy", ".."]` would append `ClipPy` to the default list.
|
||||
|
||||
Default list:

|
||||
**Default Value:** `["KiB", "MiB", "GiB", "TiB", "PiB", "EiB", "DirectX", "ECMAScript", "GPLv2", "GPLv3", "GitHub", "GitLab", "IPv4", "IPv6", "ClojureScript", "CoffeeScript", "JavaScript", "PureScript", "TypeScript", "NaN", "NaNs", "OAuth", "GraphQL", "OCaml", "OpenGL", "OpenMP", "OpenSSH", "OpenSSL", "OpenStreetMap", "OpenDNS", "WebGL", "TensorFlow", "TrueType", "iOS", "macOS", "FreeBSD", "TeX", "LaTeX", "BibTeX", "BibLaTeX", "MinGW", "CamelCase"]` (`Vec<String>`)
