Struct SpawnError

pub struct SpawnError<F>(pub F);

Error returned when a task cannot be spawned

This error is returned from Spawner’s methods when the executor has been dropped and the task cannot be spawned. The error contains the task that could not be spawned, allowing the caller to reuse the task.

SpawnError implements Debug for all F regardless of whether F does. This allows the use of unwrap and expect on Result<_, SpawnError<F>>.

Trait Implementations

impl<F: Clone> Clone for SpawnError<F>

fn clone(&self) -> SpawnError<F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F> Debug for SpawnError<F>

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

Formats the value using the given formatter.

impl<F: Default> Default for SpawnError<F>

fn default() -> SpawnError<F>

Returns the “default value” for a type.

impl<F: Hash> Hash for SpawnError<F>

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<F: Ord> Ord for SpawnError<F>

fn cmp(&self, other: &SpawnError<F>) -> 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<F: PartialEq> PartialEq for SpawnError<F>

fn eq(&self, other: &SpawnError<F>) -> 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<F: PartialOrd> PartialOrd for SpawnError<F>

fn partial_cmp(&self, other: &SpawnError<F>) -> 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.
