Struct SortOptimisations 

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

The optimisations of a sort of a cache ([Flags] enum SortOptimisations): a set of flags.

Implementations

impl SortOptimisations

pub const NONE: Self

No optimisation (None).

pub const COMPARES_IMMUTABLE_VALUES_ONLY: Self

The comparer reads values that never change, so the current position of an item is found with a binary search (ComparesImmutableValuesOnly). The comparer must also give each item a unique position.

pub const IGNORE_EVALUATES: Self

A refresh does not move items: the collection is sorted again without moves (IgnoreEvaluates).

pub const INSERT_AT_END_THEN_SORT: Self

👎Deprecated:

This is no longer being used. Use one of the other options instead.

No longer used upstream; the value of both other flags (InsertAtEndThenSort, obsolete).

pub const fn bits(self) -> u32

The flags as a number.

pub const fn has_flag(self, flag: Self) -> bool

Whether every flag of flag is set (Enum.HasFlag).

Trait Implementations

impl BitAnd for SortOptimisations

type Output = SortOptimisations

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self

Performs the & operation.

impl BitOr for SortOptimisations

type Output = SortOptimisations

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl BitOrAssign for SortOptimisations

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for SortOptimisations

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 SortOptimisations

impl Debug for SortOptimisations

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

The names of the flags, as Enum.ToString of a flags enum writes them.

impl Default for SortOptimisations

fn default() -> Self

Returns the “default value” for a type.

impl Eq for SortOptimisations

impl Hash for SortOptimisations

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 PartialEq for SortOptimisations

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

Equality operator ==.

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

Inequality operator !=.
