Struct PState 

pub struct PState { /* private fields */ }

Implementations

impl PState

pub fn new( nzbw: NonZeroUsize, op: Op<PState>, location: Option<Location>, ) -> Self

Enters a new State from the given components into the thread local arena and registers it for the current EpochCallback.

pub fn get_nzbw(&self) -> NonZeroUsize

pub fn get_op(&self) -> Op<PState>

pub fn try_get_as_usize(&self) -> Option<usize>

pub fn try_get_as_awi(&self) -> Option<Awi>

Trait Implementations

impl Clone for PState

fn clone(&self) -> PState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PState

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

Formats the value using the given formatter.

impl Default for PState

fn default() -> Self

Returns the “default value” for a type.

impl Display for PState

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

Formats the value using the given formatter.

impl Hash for PState

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 Ord for PState

fn cmp(&self, other: &PState) -> 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 PartialEq for PState

fn eq(&self, other: &PState) -> 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 PartialOrd for PState

fn partial_cmp(&self, other: &PState) -> 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.

impl Ptr for PState

type Inx = NonZero<usize>

The recommended general purpose type for this is usize

type Gen = NonZero<u64>

The recommended general purpose type for this is NonZeroU64 if generation tracking is wanted, otherwise ().

fn name() -> &'static str

The struct name used in debugging (needed by PtrNoGen for example)

fn invalid() -> Self

Returns a new Ptr with a generation value PtrGen::one(). Because the arena starts with generation 2, this is guaranteed invalid when generation counters are used. The raw index is also set to Inx::max() which should also cause failures with the generationless case, but be aware this can be reached practically with small Inx types.

fn inx(self) -> Self::Inx

Returns a raw Inx. This can be useful when getting a unique id for every entry. Do not rely on this if the Ptr is invalidated after get_raw is used.

fn generation(self) -> Self::Gen

Returns the generation of this Ptr.

fn _from_raw(inx: Self::Inx, generation: Self::Gen) -> Self

Do not use this unless you are manually managing internal details

impl Recast<PState> for PState

fn recast<R: Recaster<Item = Self>>( &mut self, recaster: &R, ) -> Result<(), <R as Recaster>::Item>

Rewrites all the <R as Recaster>::Items of self according to the <recaster as Recaster>::map.
