Struct Error

pub struct Error { /* private fields */ }

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.

Implementations

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 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 Debug for Error

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

Formats the value using the given formatter.

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

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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 Hash for Error

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

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