Rust Higher Ranked Trait Bounds . 13 Trait in Rust｜NXTEDCo., Ltd. The way we desugar this is as follows: where for<'a> F: Fn(&'a (u8, u16)) -> &'a u8, Before we dive into Higher-Rank Trait Bounds, it makes sense to briefly revisit the concept of lifetimes
Rust techniques every substrate developer should understand part Three Traits and trait bounds from subdaily.io
Bounds on an item must be satisfied when using the item which can be made into a higher-ranked trait reference
Rust techniques every substrate developer should understand part Three Traits and trait bounds The high-level idea is to replace each higher-ranked lifetime with a skolemized variable, perform the usual subtyping checks, and then check whether those skolemized variables would be. The subtyping rules for trait references that involve higher-ranked lifetimes will be defined in an analogous way to the current subtyping rules for closures Bounds on an item must be satisfied when using the item

Lifetimes in Rust are annotations that allow the compiler to ensure references are scoped correctly and that we don't run into dangling pointers or invalid references.
