Struct SystemKey 

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

A unique identifier for a system in a [ScheduleGraph].

Trait Implementations

impl Clone for SystemKey

fn clone(&self) -> SystemKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemKey

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

Formats the value using the given formatter.

impl Default for SystemKey

fn default() -> SystemKey

Returns the “default value” for a type.

impl From<KeyData> for SystemKey

fn from(k: KeyData) -> SystemKey

Converts to this type from the input type.

impl From<SystemKey> for NodeId

fn from(system: SystemKey) -> NodeId

Converts to this type from the input type.

impl GraphNodeId for SystemKey

type Adjacent = (SystemKey, Direction)

The type that packs and unpacks this GraphNodeId with a Direction. This is used to save space in the graph’s adjacency list.

type Edge = (SystemKey, SystemKey)

The type that packs and unpacks this GraphNodeId with another GraphNodeId. This is used to save space in the graph’s edge list.

fn kind(&self) -> &'static str

Name of the kind of this node id.

impl Hash for SystemKey

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Index<SystemKey> for Systems

type Output = SystemWithAccess

The returned type after indexing.

fn index(&self, key: SystemKey) -> &<Systems as Index<SystemKey>>::Output

Performs the indexing (container[index]) operation.

impl IndexMut<SystemKey> for Systems

fn index_mut( &mut self, key: SystemKey, ) -> &mut <Systems as Index<SystemKey>>::Output

Performs the mutable indexing (container[index]) operation.

impl Key for SystemKey

fn data(&self) -> KeyData

Gets the KeyData stored in this key.

fn null() -> Self

Creates a new key that is always invalid and distinct from any non-null key. A null key can only be created through this method (or default initialization of keys made with new_key_type!, which calls this method).

fn is_null(&self) -> bool

Checks if a key is null. There is only a single null key, that is a.is_null() && b.is_null() implies a == b.

impl Ord for SystemKey

fn cmp(&self, other: &SystemKey) -> 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 SystemKey

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

fn partial_cmp(&self, other: &SystemKey) -> 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 TryFrom<NodeId> for SystemKey

type Error = SystemSetKey

The type returned in the event of a conversion error.

fn try_from( value: NodeId, ) -> Result<SystemKey, <SystemKey as TryFrom<NodeId>>::Error>

Performs the conversion.
