Enum Signal

    OccursOnRequirementFacet,
    CardinalityOnRequirementFacet,
    PropertyName,

}

A shape signal observed in a document, and the revision it indicates.

Each variant is an observation, not a conclusion — a document can exhibit signals pointing at different revisions, which is precisely the case that must be reported rather than resolved.

Variants

OccursOnRequirementFacet

A requirement facet carries minOccurs / maxOccurs.

Pre-1.0: 1.0 moved occurrence onto <applicability> and gave facets @cardinality instead. This is the single most reliable tell.

CardinalityOnRequirementFacet

A requirement facet carries @cardinality.

1.0 only — the attribute does not exist before it.

PropertyName

A property facet uses <name>.

Pre-1.0: renamed to <baseName> in 1.0.

PropertyBaseName

A property facet uses <baseName>.

1.0 only.

MeasureAttribute

A property facet carries @measure.

Pre-1.0: renamed to @dataType in 1.0.

DataTypeAttribute

A property facet carries @dataType.

1.0 only.

Ifc4x3Unsuffixed

An ifcVersion lists IFC4X3.

Pre-1.0: 1.0 spells it IFC4X3_ADD2.

Ifc4x3Add2

An ifcVersion lists IFC4X3_ADD2.

1.0 only.

ClassificationWithoutSystem

A classification facet omits <system>.

Pre-1.0: <system> became required in 1.0. Weaker than the others — its presence proves nothing, since 0.9 permits it too.

Implementations

impl Signal

pub fn indicates(self) -> IdsVersion

The revision this signal indicates, or None if it only excludes 1.0.

Pre-1.0 signals cannot pick between 0.9, 0.9.6 and 0.9.7 — those revisions are not distinguished by the shapes listed here, so claiming a specific draft would be an invention. They resolve to IdsVersion::Draft0_9 as the least specific pre-1.0 revision.

pub fn is_1_0_only(self) -> bool

Whether this signal is exclusive to IDS 1.0.

Trait Implementations

impl Clone for Signal

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Signal

impl Debug for Signal

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

Formats the value using the given formatter.

impl Eq for Signal

impl Hash for Signal

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 Signal

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Signal

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Signal

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