Errors of parsing a transfer function from a string (FromStr, tf!).

Variants

UnexpectedChar

A character that is not part of the grammar.

Fields

ch: char

The character.

pos: usize

Position in the input.

InvalidNumber

A number that cannot be parsed.

Fields

text: String

The text of the number.

pos: usize

Position in the input.

UnexpectedToken

A token in the wrong place.

Fields

pos: usize

Position in the input.

expected: &'static str

What was expected instead.

UnexpectedEnd

The input ended in the middle of an expression.

Fields

expected: &'static str

What was expected.

NonIntegerExponent

A non-integer power, e.g. s^1.5.

Fields

value: f64

The exponent.

pos: usize

Position in the input.

DivisionByZero

Division by a zero polynomial.

MixedVariables

Both s and z appear.

WrongVariable

The variable does not match the domain (e.g. z when parsing a continuous-time system).

Fields

expected: char

Variable of the domain.

found: char

Variable in the input.

pos: usize

Position in the input.

Trait Implementations

impl Clone for TransferFunctionParseError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransferFunctionParseError

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

Formats the value using the given formatter.

impl Display for TransferFunctionParseError

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

Formats the value using the given formatter.

impl Error for TransferFunctionParseError

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 TransferFunctionParseError

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

Equality operator ==.

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

Inequality operator !=.
