cargo +nightly build error as unsatisfied trait bounds

[Curricane]

Describe the bug
i can not run cargo +nightly build as unsatisfied trait bounds.

To Reproduce
Steps to reproduce the behavior:

rustc version: rustc 1.76.0-nightly (a1a37735c 2023-11-23)
delay_timer commit 69a3867

1. cd delay_timer
2. cargo +nightly build

then error will show like:

error[E0277]: the trait bound `StrSearcher<'_, '_>: DoubleEndedSearcher<'_>` is not satisfied                                                                     [0/583]

It was a rust issue. ref: rust-lang/rust#100806 (comment)

The only way, aka workaround, as far as I kown, is that use Rust stable channel or use a third-part lib to fix this boundary issue: just like what I have did here: https://github.com/greenhat616/clash-verge/tree/main/backend/delay_timer

• I use str_splitter to fix this boudary issue

[DannyGoldberg]

it looks like the issue has made it into rust stable -- rust-lang/rust#100806 (comment)

I tried the same diff as you had in greenhat616/clash-verge@dc81e1c#diff-06f45ed9ebd95944143757cdbc32141be89dc35712bcb01cbf057085538917d4 and that would fix it, although it only works with cargo +nightly since str_splitter relies on nightly features
