Struct ErrorClass 

pub struct ErrorClass(/* private fields */);

Broad classification used for stable diagnostic policy.

Values are closed to the associated constants exposed by this crate. The catalog owns the class for every descriptor; error instances and domain facades cannot override it.

pub const CAPACITY: Self

Resource-capacity failure.

pub const TIMEOUT: Self

Deadline or timeout failure.

pub const UNAVAILABLE: Self

Temporarily unavailable service or resource.

pub const IO: Self

Input/output failure.

pub const DATA_CORRUPTION: Self

Corrupted or irrecoverable data.

pub const UNSUPPORTED: Self

impl Ord for ErrorClass

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ErrorClass

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ErrorClass

fn partial_cmp(&self, other: &Self) -> 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
