Trait OptionSet

pub trait OptionSet:
    Copy
    + Default
    + Eq
    + BitAnd<Output = Self>
    + BitOrAssign
    + 'static {
    const VARIANTS: &'static [Self];
    const NAMES: &'static [&'static str];
}

Trait for bit flags that forwards to std traits for useful bit operators.

Required Associated Constants

const VARIANTS: &'static [Self]

The basis flags (in the algebraic sense): one for each independent option.

const NAMES: &'static [&'static str]

The corresponding names. VARIANTS.len() == NAMES.len() must always hold.

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.
