Struct Error 

pub struct Error { /* private fields */ }

An error reported by the igraph C library, or raised by a wrapper that validated its arguments on the Rust side.

It carries the ErrorKind, the raw code, and the message, source file and line recorded by igraph’s error handler (for errors raised in Rust, the file is empty and the line is 0). Display prints <description>: <message> (<file>:<line>).

Implementations

impl Error

pub fn new(kind: ErrorKind, message: impl Into<String>) -> Self

Builds an error from its parts; mainly useful to wrappers that validate arguments on the Rust side before calling into igraph.

pub fn invalid(message: impl Into<String>) -> Self

Shorthand for an ErrorKind::InvalidValue error raised on the Rust side.

pub fn kind(&self) -> ErrorKind

The kind of this error.

pub fn code(&self) -> igraph_error_t

The raw igraph error code.

pub fn message(&self) -> &str

The human readable message reported by igraph.

pub fn file(&self) -> &str

The C source file where the error was raised (empty if unknown).

pub fn line(&self) -> i32

The C source line where the error was raised (0 if unknown).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate 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 Eq for Error

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 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.
