Trait ACMapBase 

pub trait ACMapBase {
    // Required methods
    fn with_capacity(capacity: usize) -> Self;
    fn len(&self) -> usize;
    fn clear(&mut self);

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Minimal interface for any “associative coefficient map” backing a PauliSum — construction, length, and clear.

Implementations exist for HashMap, IndexMap, and DashMap; pick one via a Config.

Required Methods

fn with_capacity(capacity: usize) -> Self

Construct an empty map with at least capacity slots reserved.

fn len(&self) -> usize

Number of stored (key, value) pairs.

fn clear(&mut self)

Remove every entry, retaining allocated capacity.

Provided Methods

fn is_empty(&self) -> bool

true if the map is empty.

Dyn Compatibility

This trait is not dyn compatible.

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