Eliding lifetimes when possible instead of specifying them directly is both shorter and easier to read. Clippy notes this in the `needless_lifetimes` lint: error: the following explicit lifetimes could be elided: 'b --> drivers/gpu/drm/drm_panic_qr.rs:479:16 | 479 | fn new<'a, 'b>(segments: &[&Segment<'b>], data: &'a mut [u8]) -> Option<EncodedMsg<'a>> { | ^^ ^^ | = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#needless_lifetimes = note: `-D clippy::needless-lifetimes` implied by `-D warnings` = help: to override `-D warnings` add `#[allow(clippy::needless_lifetimes)]` help: elide the lifetimes | 479 - fn new<'a, 'b>(segments: &[&Segment<'b>], data: &'a mut [u8]) -> Option<EncodedMsg<'a>> { 479 + fn new<'a>(segments: &[&Segment<'_>], data: &'a mut [u8]) -> Option<EncodedMsg<'a>> { | Remove the explicit lifetime annotation in favour of an elided lifetime.
