Struct HookError 

pub struct HookError { /* private fields */ }

Hook failure. Fatal errors are rare and may stop the owning loop.

Implementations

impl HookError

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

Create a non-fatal hook error.

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

Create a fatal hook error.

pub const fn is_fatal(&self) -> bool

Whether the owning loop should stop.

pub fn message(&self) -> &str

Error message.

Trait Implementations

impl Clone for HookError

fn clone(&self) -> HookError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HookError

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

Formats the value using the given formatter.

impl Display for HookError

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

Formats the value using the given formatter.

impl Eq for HookError

impl Error for HookError

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 HookError

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