Enum ObserveError 

pub enum ObserveError {
    State(ParticleStateError),
    InvalidState {
        field: &'static str,
        value: f64,
    },
}

Errors returned by particle observers.

Variants

State(ParticleStateError)

InvalidState

Numeric state violates an observer precondition.

Fields

field: &'static str

Name of the state field with invalid value.

value: f64

Invalid numeric value encountered by the observer.

Trait Implementations

impl Clone for ObserveError

fn clone(&self) -> ObserveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObserveError

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

Formats the value using the given formatter.

impl Display for ObserveError

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

Formats the value using the given formatter.

impl Error for ObserveError

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.

fn from(value: AttrsError) -> Self

Converts to this type from the input type.

impl From<ParticleStateError> for ObserveError

fn from(value: ParticleStateError) -> Self

impl PartialEq for ObserveError

fn eq(&self, other: &ObserveError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
