Struct DemandKey 

pub struct DemandKey {
    pub supply_type: TypeId,
    pub variable_name: String,
    pub discriminator: Option<String>,
}

A unique key identifying a supply demand.

The key combines the supply type with the variable it tracks, allowing multiple supplies of the same type for different variables.

Fields

supply_type: TypeId

The type of supply being requested.

variable_name: String

The name of the variable this supply tracks.

discriminator: Option<String>

Optional discriminator for multiple supplies of the same type/variable.

Implementations

impl DemandKey

pub fn new<S: Supply>(variable_name: impl Into<String>) -> Self

Creates a new demand key.

pub fn with_discriminator<S: Supply>( variable_name: impl Into<String>, discriminator: impl Into<String>, ) -> Self

Creates a demand key with a discriminator.

Trait Implementations

impl Clone for DemandKey

fn clone(&self) -> DemandKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DemandKey

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

Formats the value using the given formatter.

impl Hash for DemandKey

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 DemandKey

fn eq(&self, other: &DemandKey) -> 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.
