Enum ErrorCode 

#[non_exhaustive]
#[repr(u16)]
pub enum ErrorCode {
    InvalidPlan = 1,
    ParkFallback = 2,
    ExecutorFallback = 3,
    ExecutorRefused = 4,
    InvalidExecutor = 5,
    PendedInline = 6,
    Stalled = 7,
    Backend = 8,
}

The identity of an Error: append-only, a number is never reused.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidPlan = 1

A wait-plan or band text that does not parse: (subject, the text and the fault).

ParkFallback = 2

A requested park the host cannot run, and the declared fallback that runs instead: (requested plan, missing capability, why, the plan that runs). A warning.

ExecutorFallback = 3

A requested executor the host cannot run, and the declared fallback that runs instead: (requested, why, the executor that runs). A warning.

ExecutorRefused = 4

A requested executor the host cannot run while the setting is strict: (requested, why).

InvalidExecutor = 5

An executor name that is not one of the declared kinds: (the text, the accepted names).

PendedInline = 6

A future pended on a host that completes every future on its first poll: (the site).

Stalled = 7

The executor has unfinished tasks and nothing to wait on: (tasks left).

Backend = 8

A backend call failed: (the call, the vendor status).

Implementations

impl ErrorCode

pub const ALL: &'static [ErrorCode]

Every code, in registry order.

pub const fn form(self) -> &'static str

The form template: each {} takes one argument, in order.

pub const fn number(self) -> u16

The stable number.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorCode

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl Hash for ErrorCode

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 ErrorCode

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 ErrorCode

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ErrorCode

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
