Stuart Cook 3e3db73c9b Rollup merge of #134737 - estebank:deive-lint-default-fields-base, r=compiler-errors ... Implement `default_overrides_default_fields` lint Detect when a manual `Default` implementation isn't using the existing default field values and suggest using `..` instead: ``` error: `Default` impl doesn't use the declared default field values --> $DIR/manual-default-impl-could-be-derived.rs:14:1 | LL | / impl Default for A { LL | | fn default() -> Self { LL | | A { LL | | y: 0, | | - this field has a default value ... | LL | | } | |_^ | = help: use the default values in the `impl` with `Struct { mandatory_field, .. }` to avoid them diverging over time note: the lint level is defined here --> $DIR/manual-default-impl-could-be-derived.rs:5:9 | LL | #![deny(default_overrides_default_fields)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ``` r? `@compiler-errors` This is a simpler version of #134441, detecting the simpler case when a field with a default should have not been specified in the manual `Default::default()`, instead using `..` for it. It doesn't provide any suggestions, nor the checks for "equivalences" nor whether the value used in the imp being used would be suitable as a default field value.		2024-12-28 16:50:36 +11:00
