Enum Error 

#[non_exhaustive]
pub enum Error {
    Config(String),
    Shape(String),
    Numerical(String),
    Condition(String),
    Io(Error),
}

The error of every fallible operation of comnum.

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.

Config(String)

A parameter is outside its domain (the message names it and its value).

Shape(String)

Two inputs have inconsistent lengths or shapes.

Numerical(String)

A numerical routine failed (non-finite value, singular system, no convergence).

Condition(String)

A simulation condition does not hold the requested key, or holds another type.

Io(Error)

An input/output error (a logger, a recording).

Implementations

impl Error

pub fn context(self, context: impl Display) -> Error

The same error with context prepended to its message (the kind is kept, so that a configuration error found while building a condition stays one).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.
