Path expressions
Syntax
PathExpression :
PathInExpression
| QualifiedPathInExpression
A path used as an expression context denotes either a local variable or an item.
Path expressions that resolve to local or static variables are place expressions, other paths are value expressions.
Using a static mut
variable requires an unsafe
block.
#![allow(unused)] fn main() { mod globals { pub static STATIC_VAR: i32 = 5; pub static mut STATIC_MUT_VAR: i32 = 7; } let local_var = 3; local_var; globals::STATIC_VAR; unsafe { globals::STATIC_MUT_VAR }; let some_constructor = Some::<i32>; let push_integer = Vec::<i32>::push; let slice_reverse = <[i32]>::reverse; }
