Enum ErrorKind 

pub enum ErrorKind {
    Execution,
    ParamResolution,
}

Classification of the error that caused a system failure.

Used in CaughtError to distinguish error sources without parsing message strings.

Examples

use polaris_graph::ErrorKind;

let kind = ErrorKind::Execution;
assert_eq!(format!("{kind}"), "execution");

let kind = ErrorKind::ParamResolution;
assert_eq!(format!("{kind}"), "param_resolution");

Variants

Execution

System returned Err(SystemError::ExecutionError(...)).

ParamResolution

System parameter resolution failed (Err(SystemError::ParamError(...))).

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorKind

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl PartialEq for ErrorKind

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