Enum Attribute 

pub enum Attribute {
    Integer(i64),
    Real(f64),
    String(String),
    Enum(String),
    Binary(String),
    EntityRef(u64),
    Unset,
    Derived,
    List(Vec<Attribute>),
    Typed {
        type_name: String,
        value: Box<Attribute>,
    },
}

A parsed attribute value from a Part 21 entity instance.

Covers every construct allowed in a parameter position by ISO 10303-21.

Variants

Integer(i64)

Real(f64)

String(String)

String with outer quotes stripped. The '' escape is decoded to a single ' by the lexer. Wide-char escapes (\X\HH, \X2\...\X0\) are not decoded — that step is deferred to a later stage.

Enum(String)

Enumeration value without the surrounding dots (e.g. .T. → "T").

Binary(String)

Hex-encoded binary without the surrounding quotes.

EntityRef(u64)

Entity reference #N.

Unset

Unset / omitted attribute ($).

Derived

Derived attribute (*).

List(Vec<Attribute>)

Parenthesised list of parameters. May be nested.

Typed

Typed parameter such as LENGTH_MEASURE(1.E-07).

Fields

type_name: String

value: Box<Attribute>

Trait Implementations

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attribute

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

Formats the value using the given formatter.

impl PartialEq for Attribute

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