Enum UtilsError 

pub enum UtilsError {
    InvalidValue(String),
    NumericConversion(String),
}

Error type used by generic utility helpers.

Variants

InvalidValue(String)

A value failed semantic validation.

NumericConversion(String)

A numeric conversion would overflow, underflow, or lose sign information.

Implementations

impl UtilsError

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

Creates an invalid-value error.

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

Creates a numeric-conversion error.

Trait Implementations

impl Clone for UtilsError

fn clone(&self) -> UtilsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UtilsError

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

Formats the value using the given formatter.

impl Display for UtilsError

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

Formats the value using the given formatter.

impl Error for UtilsError

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 UtilsError

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