rust - Unable to create hyper::Client because the compiler cannot infer enough type information -

to experiment hyper, started the example. aside fact example doesn't compile (no method `get` in `client`) have distilled problem single line:

fn temp() {     let client = client::new(); } 

this code won't compile:

 unable infer enough type information `_`; type annotations or generic parameter binding required [e0282] 

in general error mean client has generic parameter , compiler can not infer it's value. have tell somehow.

here example std::vec::vec:

use std::vec::vec;  fn problem() {     let v = vec::new(); // problem, vec<???> want? }  fn solution_1() {     let mut v = vec::<i32>::new(); // tell compiler directly }  fn solution_2() {     let mut v: vec<i32> = vec::new(); // tell compiler specifying type }  fn solution_3() {     let mut v = vec::new();     v.push(1); // tell compiler using } 

but hyper::client::client doesn't have generic parameters. sure client trying instantiate 1 hyper?
