Enum CwtPaddingMode 

#[non_exhaustive]
pub enum CwtPaddingMode {
    Zero,
    Reflect,
    Periodic,
}

CWT boundary-padding mode for the productized phase-coherence signal.

All three modes share the same pad-and-strip pipeline: the input is extended by pad_len samples on each side using the chosen rule, the underlying CWT runs on the extended signal, then the boundary cells are stripped from each per-period row. The signal pins the FFT-based CWT backend (ferro_wave::transform::cwt_fft); for input lengths that are not a power of two, that backend internally zero-pads to next_power_of_two on top of the explicit extension. Small artifacts can therefore leak into the strip’s edge cells regardless of the chosen mode — the cwt_padding metadata names the explicit extension applied at the original window length, not the FFT backend’s internal padding.

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.

Zero

Pad with zeros outside the signal.

Reflect

Reflect the signal at the boundary using a whole-sample symmetric mirror (the boundary samples appear twice).

Periodic

Wrap circularly across the boundary at the original window length. (See the enum-level note for the FFT backend’s internal next_power_of_two zero-pad.)

Implementations

impl CwtPaddingMode

pub fn as_str(self) -> &'static str

Stable wire-friendly identifier.

Trait Implementations

impl Clone for CwtPaddingMode

fn clone(&self) -> CwtPaddingMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CwtPaddingMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CwtPaddingMode

fn default() -> CwtPaddingMode

Returns the “default value” for a type.

impl PartialEq for CwtPaddingMode

fn eq(&self, other: &CwtPaddingMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
