Enum WaveletFamily 

#[non_exhaustive]
pub enum WaveletFamily {
    Haar,
    Daubechies(usize),
}

A wavelet family: Haar (db1) or Daubechies of a given vanishing-moment order.

Daubechies(N) carries the vanishing-moment order N ∈ 2..=10 (db2..db10); db1 is spelled WaveletFamily::Haar. Construct from a plain dbN order via WaveletFamily::from_db_order.

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.

Haar

The Haar wavelet (equivalently db1): filter length 2.

Daubechies(usize)

Daubechies wavelet with N vanishing moments (N ∈ 2..=10, filter length 2N).

Implementations

impl WaveletFamily

pub fn from_db_order(order: usize) -> Result<Self, FdarError>

Map a plain Daubechies order to a WaveletFamily.

1 maps to WaveletFamily::Haar (db1 == Haar); 2..=10 map to WaveletFamily::Daubechies.

Errors

Returns FdarError::InvalidParameter for an order of 0 or > 10.
