bors 73be4863f0 Auto merge of #12459 - y21:unconditional_recursion_from_into, r=Jarcho ... lint when calling the blanket `Into` impl from a `From` impl Closes #11150 ``` warning: function cannot return without recursing --> x.rs:9:9 | 9 | / fn from(value: f32) -> Self { 10 | | value.into() 11 | | } | |_________^ | note: recursive call site --> x.rs:10:13 | 10 | value.into() | ^^^^^^^^^^^^ ``` I'm also thinking that we can probably generalize this lint to #11032 at some point (instead of hardcoding a bunch of impls), like how rustc's `unconditional_recursion` works, at least up to one indirect call, but this still seems useful for now :) I've also noticed that we use `fn_def_id` in a bunch of lints and then try to get the node args of the call in a separate step, so I made a helper function that does both in one. I intend to refactor a bunch of uses of `fn_def_id` to use this later I can add more test cases, but this is already using much of the same logic that exists for the other impls that this lint looks for (e.g. making sure that there are no conditional returns). changelog: [`unconditional_recursion`]: emit a warning inside of `From::from` when unconditionally calling the blanket `.into()` impl		2024-03-13 16:32:25 +00:00
