Struct FallbackTryDropStrategyHandler 

pub struct FallbackTryDropStrategyHandler<FDS, FTDS>
where
    FDS: TryDropStrategy,
    FTDS: FallibleTryDropStrategy,
{
    pub fallback_try_drop_strategy: FDS,
    pub fallible_try_drop_strategy: FTDS,
}

A type which chains two try drop strategies together, one of which may fail and if so, will be redirected to the fallback, infallible try drop strategy.

This type implements TryDropStrategy because, as said before, any and all errors in the fallible try drop strategy will be redirected to the fallback, which can never fail.

Fields

fallback_try_drop_strategy: FDS

The fallback try drop strategy. This will be called if the first try drop strategy fails and is a last resort to recovering sanely.

fallible_try_drop_strategy: FTDS

The try drop strategy which may fail. This will be called first.

where FDS: TryDropStrategy + Clone, FTDS: FallibleTryDropStrategy + Clone,

fn clone(&self) -> FallbackTryDropStrategyHandler<FDS, FTDS>

Returns a duplicate of the value.

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

where FDS: TryDropStrategy + Default, FTDS: FallibleTryDropStrategy + Default,

fn default() -> FallbackTryDropStrategyHandler<FDS, FTDS>

Returns the “default value” for a type.

impl<FDS, FTDS> Hash for FallbackTryDropStrategyHandler<FDS, FTDS>

where FDS: TryDropStrategy + Hash, FTDS: FallibleTryDropStrategy + Hash,

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,

impl<FDS, FTDS> Ord for FallbackTryDropStrategyHandler<FDS, FTDS>

where FDS: TryDropStrategy + Ord, FTDS: FallibleTryDropStrategy + Ord,

fn cmp(&self, other: &FallbackTryDropStrategyHandler<FDS, FTDS>) -> 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<FDS, FTDS> PartialEq for FallbackTryDropStrategyHandler<FDS, FTDS>

where FDS: TryDropStrategy + PartialEq, FTDS: FallibleTryDropStrategy + PartialEq,

fn eq(&self, other: &FallbackTryDropStrategyHandler<FDS, FTDS>) -> 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.

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.
