Rust includes two kinds of "fat pointers": references to slices, and trait objects. A reference to a slice carries the starting address of the slice and its length. A trait object carries a value's address and a pointer to the trait's implementation appropriate to that value.

LTO   | Short for Link-Time Optimizations, this is a set of optimizations offered by LLVM that occur just before the final binary is linked. These include optimizations like removing functions that are never used in the final program, for example. _ThinLTO_ is a variant of LTO that aims to be a bit more scalable and efficient, but possibly sacrifices some optimizations. You may also read issues in the Rust repo about "FatLTO", which is the loving nickname given to non-Thin LTO. LLVM documentation: [here][lto] and [here][thinlto]. [LLVM]   | (actually not an acronym :P) an open-source compiler backend. It accepts LLVM IR and outputs native binaries. Various languages (e.g. Rust) can then implement a compiler front-end that outputs LLVM IR and use LLVM to compile to all the platforms LLVM supports. diff --git a/src/borrow_check/region_inference/lifetime_parameters.md b/src/borrow_check/region_inference/lifetime_parameters.md index 2dbbc0c1e..bd8a07843 100644 --- a/src/borrow_check/region_inference/lifetime_parameters.md +++ b/src/borrow_check/region_inference/lifetime_parameters.md @@ -43,8 +43,8 @@ only variant of [`ty::RegionKind`] that we use is the [`ReVar`] variant.
