WebI want to write a simple benchmark for HashMap, to compare it to rust-phf. The benchmark code looks like this: b.iter( kw_existing.iter().map( s KEYWORDS.find(s))); where KEYWORDS is a static PhfMap and kw_existing an array of all keywords. This works fine. However, the analogous code for HashMap does not: Web8. aug 2024 · Rust-PHF is a library to generate efficient lookup tables at compile time using perfect hash functions. It currently uses the CHD algorithm and can generate a 100,000 entry map in roughly .4 seconds. By default statistics are not produced, but if you set the environment variable PHF_STATS it will issue a compiler note about how long it took. burger king whopper cost

"Webphf HashMap uses a somewhat slow hash algorithm (quoting the documentation) to avoid DoS attacks. With large enough maps there's also a possibility of collisions. On the other hand, phf uses perfect hashing (hashing that guarantees no collisions) to build compile-time maps. This way we can have efficient constant-time lookups at runtime. " - Phf rust

The implementation of the macro needs to know the actual values of the keys to calculate the lookup tables for the map, but unfortunately the macros can't inspect the values of the consts, all they see are the names.

WebPanic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.. Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end.
