Enum RootError 

pub enum RootError<E = Infallible> {
    InvalidInput {
        field: &'static str,
        reason: &'static str,
    },
    Predicate(E),
}

Error returned when scalar root-bracketing inputs leave the finite domain.

Variants

InvalidInput

A scalar endpoint, sample, or midpoint value was non-finite.

Fields

field: &'static str

Name of the malformed field.

reason: &'static str

Stable validation reason.

Predicate(E)

The caller-provided fallible predicate returned an error.

Trait Implementations

impl<E: Clone> Clone for RootError<E>

fn clone(&self) -> RootError<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for RootError<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for RootError<E>

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

Formats the value using the given formatter.

impl<E: Eq> Eq for RootError<E>

impl<E: Debug + Display> Error for RootError<E>

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<E: PartialEq> PartialEq for RootError<E>

fn eq(&self, other: &RootError<E>) -> 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.
