Trait DepthCounter 

pub trait DepthCounter: Debug + Copy {
    // Required methods
    fn zero() -> Self;
    fn increment(self) -> (Self, bool);
    fn decrement(self) -> (Self, bool);
    fn is_zero(self) -> bool;
}

Trait for depth counters - tracks nesting depth.

This trait provides overflow-safe operations for tracking JSON nesting depth. Implemented for all unsigned integer types.

Required Methods

fn zero() -> Self

Create a zero depth value

fn increment(self) -> (Self, bool)

Increment depth, returning (new_value, overflow_occurred)

fn decrement(self) -> (Self, bool)

Decrement depth, returning (new_value, underflow_occurred)

fn is_zero(self) -> bool

Check if depth is zero

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
