Enum BoundaryMode 

#[non_exhaustive]
pub enum BoundaryMode {
    Periodic,
    Symmetric,
}

Boundary handling for the single-level convolution/downsampling step.

Analysis and synthesis are an exact adjoint pair under each mode independently, so the single-level round-trip reconstructs perfectly regardless of the mode.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Periodic

Circular (periodic) extension: indices wrap around modulo n.

Symmetric

Half-point symmetric extension: indices reflect at the boundaries.
