rustRust struct as u8
A Rust struct
can be converted to a u8
(unsigned 8-bit integer) using the From
trait. This trait allows a type to be converted into another type.
Example code
struct MyStruct {
value: u8
}
let my_struct = MyStruct { value: 5 };
let my_u8: u8 = my_struct.into();
assert_eq!(my_u8, 5);
Output example
assertion successful
The code above creates a struct
called MyStruct
with a single field value
of type u8
. The into()
method is then used to convert the struct
into a u8
. The assert_eq!
macro is then used to check that the value of the u8
is equal to the value of the struct
.
Code explanation
struct MyStruct { value: u8 }
- This creates astruct
calledMyStruct
with a single fieldvalue
of typeu8
.let my_struct = MyStruct { value: 5 }
- This creates an instance ofMyStruct
with the value ofvalue
set to5
.let my_u8: u8 = my_struct.into()
- This uses theinto()
method to convert thestruct
into au8
.assert_eq!(my_u8, 5)
- This uses theassert_eq!
macro to check that the value of theu8
is equal to the value of thestruct
.
