Struct apint::Error

pub struct Error { /* fields omitted */ }

Represents an error that may occure upon using the ApInt library.

All errors have a unique kind which also stores extra information for error reporting. Besides that an Error also stores a message and an optional additional annotation.

Methods

impl Error

Public getters for Error. ===========================================================================

pub fn kind(&self) -> &ErrorKind

Returns a reference to the kind of this Error.

pub fn message(&self) -> &str

Returns the error message description of this Error.

pub fn annotation(&self) -> Option<&str>

Returns the optional annotation of this Error.

Trait Implementations

impl Debug for Error

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Error

fn eq(&self, __arg_0: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Error) -> bool

This method tests for !=.

impl Eq for Error

impl Hash for Error

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl<T> Into<Result<T>> for Error

fn into(self) -> Result<T>

Converts an Error into a Result<T, Error>.

This might be useful to prevent some parentheses spams because it replaces Err(my_error) with my_error.into().

On the other hand it might be an abuse of the trait ...

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

A short description of the error.

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

The lower-level cause of this error, if any.
