use of End Array.

[doronb4637]

Hello i want to use an end array like in this example, but the code doesn't compile and i couldn't find any source to help, any ideas?
#[derive(Debug, PartialEq, DekuRead, DekuWrite)]
pub struct EndArrayExample {
pub bools: Vec<E_Boolean>,
}

E_Boolean:
#[derive(Debug, PartialEq, DekuRead, DekuWrite)]
#[deku(id_type = "u8",ctx = "bit_size: usize",ctx_default = "8", bits = "bit_size")]
#[repr(u8)]
enum E_Boolean {
False = 0,
True = 1,
}
