Hello all.
I'm trying to dig into Rust world, but stuck into problems at the very beginning. According to the manuals and book and samples, code:
use std::collections::HashMap;
use std::hash::Hash;
fn main() {
let mut hmap = HashMap::new;
hmap.insert("hello", "world");
println!("{}", hmap.get("hello").unwrap());
}
should just work. But it does not even compile:
$ rustc main.rs
main.rs:6:10: 6:34 error: type `fn() -> std::collections::hash::map::HashMap<_, _> {std::collections::hash::map::HashMap<K, V, RandomState>::new}` does not implement any method in scope named `insert`
main.rs:6 hmap.insert("hello", "world");
^~~~~~~~~~~~~~~~~~~~~~~~
main.rs:7:25: 7:37 error: type `fn() -> std::collections::hash::map::HashMap<_, _> {std::collections::hash::map::HashMap<K, V, RandomState>::new}` does not implement any method in scope named `get`
main.rs:7 println!("{}", hmap.get("hello").unwrap());
^~~~~~~~~~~~
error: aborting due to 2 previous errors
Probably this is because some recent changes into the language, but what is a place to look for them?
Sorry for stupid question, but I'm ever does not know a better place to ask it.
