Enum ZTransformError 

pub enum ZTransformError {
    NoRule(String),
    NotInvertible(String),
    SameVariable,
}

Errors from the Z-transform routines.

Variants

NoRule(String)

No forward rule matched a[n] (E-TRANSFORM-101).

NotInvertible(String)

The inverse-transform input is not a form the table can invert (E-TRANSFORM-102).

SameVariable

The frequency variable z and discrete-index variable n must be distinct symbols (E-TRANSFORM-103).

Trait Implementations

impl Clone for ZTransformError

fn clone(&self) -> ZTransformError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZTransformError

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

Formats the value using the given formatter.

impl Display for ZTransformError

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

Formats the value using the given formatter.

impl Eq for ZTransformError

impl Error for ZTransformError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ZTransformError

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