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 astructcalledMyStructwith a single fieldvalueof typeu8.let my_struct = MyStruct { value: 5 }- This creates an instance ofMyStructwith the value ofvalueset to5.let my_u8: u8 = my_struct.into()- This uses theinto()method to convert thestructinto au8.assert_eq!(my_u8, 5)- This uses theassert_eq!macro to check that the value of theu8is equal to the value of thestruct.
