Struct Flags 

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

Planning flags that control algorithm selection.

Implementations

impl Flags

pub const ESTIMATE: Self

Use heuristics only, don’t measure (fastest planning, may not be optimal).

pub const MEASURE: Self

Measure a few algorithms and pick the best.

pub const PATIENT: Self

Try harder to find the optimal algorithm.

pub const EXHAUSTIVE: Self

Try all possible algorithms exhaustively.

pub const PRESERVE_INPUT: Self

Preserve input array (default behavior).

pub const DESTROY_INPUT: Self

Allow destroying input array for potentially better performance.

pub const UNALIGNED: Self

Plan for unaligned data.

pub const fn is_measure(self) -> bool

Check if MEASURE flag is set.

pub const fn is_patient(self) -> bool

Check if PATIENT flag is set.

pub const fn is_exhaustive(self) -> bool

Check if EXHAUSTIVE flag is set.

pub const fn can_destroy_input(self) -> bool

Check if input destruction is allowed.

Trait Implementations

impl BitOr for Flags

type Output = Flags

The resulting type after applying the | operator.

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

Performs the | operation.

impl Clone for Flags

fn clone(&self) -> Flags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Flags

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

Formats the value using the given formatter.

impl Default for Flags

fn default() -> Flags

Returns the “default value” for a type.

impl Hash for Flags

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 Flags

fn eq(&self, other: &Flags) -> 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 Flags

impl Eq for Flags

impl StructuralPartialEq for Flags
