Enum FilterSpec 

pub enum FilterSpec {
    Bandpass {
        fl: Flt,
        fu: Flt,
        order: u32,
    },
    Lowpass {
        fc: Flt,
        order: u32,
    },
    Highpass {
        fc: Flt,
        order: u32,
    },
}

Specification of a filter for a certain type.

The order corresponds to the rolloff in dB/decade. order=1 means 20 dB/dec, order=2 40 dB/dec and so on. For a bandpass filter, the order also corresponds to the roll-off and roll-on of the filter. For this case, the order is not ‘shared’ between the highpass and lowpass part.

Variants

Bandpass

Bandpass filter. Cuton frequency fl in [Hz]. Cutoff frequency fu in [Hz]. Typically implemented as a highpass combined with a lowpass.

Fields

fl: Flt

Lower cut-on frequency [Hz]

fu: Flt

Higher cut-off frequency [Hz]

order: u32

Filter order n*20 dB/dec roll-on and off

Lowpass

Lowpass filter. Cutoff frequency fc in [Hz].

Fields

fc: Flt

Cut-off frequency [Hz]

order: u32

Filter order n*20 dB/dec roll-on and off

Highpass

Highpass filter. Cuton frequency fc in [Hz].

Fields

fc: Flt

Cut-on frequency [Hz]

order: u32

Filter order n*20 dB/dec roll-on and off

Trait Implementations

impl Clone for FilterSpec

fn clone(&self) -> FilterSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterSpec

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

Formats the value using the given formatter.

impl<'py> IntoPyObject<'py> for FilterSpec

type Target = FilterSpec

The Python output type

type Output = Bound<'py, <FilterSpec as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PartialEq for FilterSpec

fn eq(&self, other: &FilterSpec) -> 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.

impl PyClass for FilterSpec

type Frozen = True

Whether the pyclass is frozen.

impl PyClassBaseType for FilterSpec

type LayoutAsBase = PyClassObject<FilterSpec>

type BaseNativeType = <FilterSpec as PyClassImpl>::BaseNativeType

type Initializer = PyClassInitializer<FilterSpec>

type PyClassMutability = <FilterSpec as PyClassImpl>::PyClassMutability

impl PyClassImpl for FilterSpec

const IS_BASETYPE: bool = true

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

const IS_IMMUTABLE_TYPE: bool = false

#[pyclass(immutable_type)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<FilterSpec>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::ImmutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

fn items_iter() -> PyClassItemsIter

fn doc(py: Python<'_>) -> PyResult<&'static CStr>

Rendered class doc

fn lazy_type_object() -> &'static LazyTypeObject<Self>

fn dict_offset() -> Option<isize>

fn extract( obj: &'a Bound<'py, PyAny>, holder: &'a mut Self::Holder, ) -> PyResult<Self>

impl PyTypeInfo for FilterSpec

const NAME: &'static str = "FilterSpec"

Class name.

const MODULE: Option<&'static str> = ::core::option::Option::None

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn type_object(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.

fn is_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
