The `type_of` function detects the actual type of a value.
|
||
|
|
|
||
|
|
This is useful because all variables are [`Dynamic`] in nature.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
// Use 'type_of()' to get the actual types of values
|
||
|
|
type_of('c') == "char";
|
||
|
|
type_of(42) == "i64";
|
||
|
|
|
||
|
|
let x = 123;
|
||
|
|
x.type_of() == "i64"; // method-call style is also OK
|
||
|
|
type_of(x) == "i64";
|
||
|
|
|
||
|
|
x = 99.999;
|
||
|
|
type_of(x) == "f64";
|
||
|
|
|
||
|
|
x = "hello";
|
||
|
|
if type_of(x) == "string" {
|
||
|
|
do_something_with_string(x);
|
||
|
|
}
|
||
|
|
```
