Trait PolicyId 

pub trait PolicyId:
    Copy
    + Clone
    + Debug
    + Eq
    + Hash
    + Ord
    + PartialOrd {
    // Required methods
    fn as_u32(&self) -> u32;
    fn from_u32(value: u32) -> Option<Self>;
}

Trait for strongly-typed policy identifiers.

Types implementing PolicyId can be parsed from and serialized to u32 values in the binary policy database, but are represented as strongly-typed integers (often wrapping NonZeroU16 or NonZeroU32) in the logical domain model.

Required Methods

fn as_u32(&self) -> u32

Returns the raw u32 value of the ID.

fn from_u32(value: u32) -> Option<Self>

Constructs an instance of Self from a raw u32 value, returning None if the value is invalid (e.g. zero for a non-optional ID, or out of range).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
