Error code E0154
Note: this error code is no longer emitted by the compiler.
Imports (use
statements) are not allowed after non-item statements, such as
variable declarations and expression statements.
Here is an example that demonstrates the error:
#![allow(unused)] fn main() { fn f() { // Variable declaration before import let x = 0; use std::io::Read; // ... } }
The solution is to declare the imports at the top of the block, function, or file.
Here is the previous example again, with the correct order:
#![allow(unused)] fn main() { fn f() { use std::io::Read; let x = 0; // ... } }
See the Declaration Statements section of the reference for more information about what constitutes an item declaration and what does not.
