A typed reference read by a residual expression.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Field(Id<Field>)

Current value of a Field.

Derivative(Id<Field>, NonZero<u32>)

Time derivative of a Field, of a given positive order. Reduction to first order keeps the source Field’s identity; the derivative coordinates it introduces are not separate authored Fields.

Pre(Id<Field>)

Value immediately before the current activation instant.

Next(Id<Field>)

Value solved simultaneously for the next discrete state.

Parameter(Id<Parameter>)

Immutable or design Parameter value.

Observable(Id<Observable>)

Value of a derived Observable, read by another Observable or an admitted Relation.

Outcome(Id<Relation>)

Named outcome of an exact finite probability law, bound only while integrating a random variable. Reading it never draws from a generator.

Port(Id<Port>)

Value carried by a typed Port.

Across(Id<Port>)

Across variable of a scalar physical Port.

Through(Id<Port>)

Through variable, positive from a junction into the owning Relation.

PortTrace(Id<Port>)

Trace quantity of a field-valued boundary physical Port.

PortFlux(Id<Port>)

Outward flux quantity of a field-valued boundary physical Port.

Coordinate

A coordinate projection, independent of temporal activation.

Fields

support: Id<Domain>

Domain on which this projection is defined.

factor: Id<Domain>

Factor Domain, or the physical parent for a boundary projection.

axis: usize

Axis index within that factor, not within the flattened product.

Time

Model time in seconds.

Trait Implementations

§

impl Clone for SymbolRef

Signature links:CloneSymbolRef

§

fn clone(&self) -> SymbolRef

Signature links:cloneSymbolRef

Returns a duplicate of the value.

§

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

Signature links:unstableSourceclone_from

Performs copy-assignment from source.

§

impl Debug for SymbolRef

Signature links:DebugSymbolRef

§

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

Signature links:fmtFormatterResult()Error

Formats the value using the given formatter.

§

impl Hash for SymbolRef

Signature links:HashSymbolRef

§

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

where __H: Hasher,

Signature links:hash&mut __HHasher

Feeds this value into the given Hasher.

§

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Signature links:Sourcehash_slice&mut HHasherSized

Feeds a slice of this type into the given Hasher.

§

impl PartialEq for SymbolRef

Signature links:PartialEqSymbolRef

§

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

Signature links:eqSymbolRefbool

Tests for self and other values to be equal, and is used by ==.

§

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

Signature links:unstableSourcene&Rhsbool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
