Witrynavec![] is equivalent to Vec::new(), which for a generic type T is of type Vec. Rust practices local inference; by the time compilation is complete, the type T must be known—hence fn main() { let foo = vec![]; } fails. But Rust’s quite willing to leave it unresolved at definition time and figure out what it is from later usage.

WitrynaMore often, you’ll create a Vec with initial values and Rust will infer the type of value you want to store, so you rarely need to do this type annotation.
