Enum DropPolicy 

#[non_exhaustive]
pub enum DropPolicy {
    MayDropContents,
    MustNotDropContents,
}

Determines what happens when a pool is dropped when there are still objects in that pool.

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.

MayDropContents

The pool will drop any objects within when the pool is dropped. This is the default.

MustNotDropContents

The pool will panic if it still contains objects when it is dropped.

This may be valuable if there are external requirements before the objects can be dropped. For example, it may be known that unsafe code is used to create out of band references to the objects, with objects only removed after such references have been dropped.

Trait Implementations

impl Clone for DropPolicy

fn clone(&self) -> DropPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DropPolicy

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

Formats the value using the given formatter.

impl Default for DropPolicy

fn default() -> DropPolicy

Returns the “default value” for a type.

impl PartialEq for DropPolicy

fn eq(&self, other: &DropPolicy) -> 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 Copy for DropPolicy
