Trait VirtualStaticBound

pub trait VirtualStaticBound<Discriminant: DiscriminantTag = ()> {
    const BOUND: usize;
}

Provides the bounds associated with a VirtualStaticField<Discriminant>.

VirtualStaticBound defines constraints (such as capacity limits) that are fully determined at compile time.

Representation

The bound is provided as a const, meaning:

• it is a compile-time constant
• no runtime resolution or indirection is involved

This enables fully static, zero-overhead representations.

Discriminant

The Discriminant links a field to its corresponding bound, allowing multiple independent fields to coexist without ambiguity.

Default Discriminant

• Discriminant = (): provides a single default bound, meaning only one dynamically bounded field is assumed.

Required Associated Constants

const BOUND: usize

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.

Implementations on Foreign Types

impl VirtualStaticBound for ()

No-op bound provided with zero capacity.
