Expected type did not match the received type.
Erroneous code examples:
fn plus_one(x: i32) -> i32 {
x + 1
}
plus_one("Not a number");
// ^^^^^^^^^^^^^^ expected `i32`, found `&str`
if "Not a bool" {
// ^^^^^^^^^^^^ expected `bool`, found `&str`
}
let x: f32 = "Not a float";
// --- ^^^^^^^^^^^^^ expected `f32`, found `&str`
// |
// expected due to this
RunThis error occurs when an expression was used in a place where the compiler expected an expression of a different type. It can occur in several cases, the most common being when calling a function and passing an argument which has a different type than the matching type in the function declaration.
