Enum ErrBoxCheckFailure

pub enum ErrBoxCheckFailure {
    ResultIsNotErr,
    DowncastFailed,
    NotEqual {
        expected: String,
        actual: String,
    },
}

Unsuccessful outcome of check_err_box.

Variants

ResultIsNotErr

If the tested Result is Ok instead of Err.

DowncastFailed

If the wrapped Error cannot be downcast to the expected error type.

NotEqual

If the wrapped Error is not equal (via PartialEq) to the expected error.

Fields

expected: String

actual: String

Trait Implementations

impl Clone for ErrBoxCheckFailure

fn clone(&self) -> ErrBoxCheckFailure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrBoxCheckFailure

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

Formats the value using the given formatter.

impl Display for ErrBoxCheckFailure

use dyn_error::*;

assert_eq!(
    ErrBoxCheckFailure::ResultIsNotErr.to_string(),
    "The result is not Err."
);

assert_eq!(
    ErrBoxCheckFailure::DowncastFailed.to_string(),
    "The boxed error cannot be downcast to the expected type."
);

assert_eq!(
    ErrBoxCheckFailure::NotEqual {
        expected: "EXP".to_string(),
        actual: "ACT".to_string()
    }.to_string(),
    "Expected error: 'EXP', actual error: 'ACT'."
);

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

Formats the value using the given formatter.

impl Error for ErrBoxCheckFailure

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 Hash for ErrBoxCheckFailure

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ErrBoxCheckFailure

fn cmp(&self, other: &ErrBoxCheckFailure) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ErrBoxCheckFailure

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

impl PartialOrd for ErrBoxCheckFailure

fn partial_cmp(&self, other: &ErrBoxCheckFailure) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
