Decoded attribute value

Represents any value that can appear in an IFC entity’s attribute list.

Variants

Entity reference (#123)

Bool(bool)

Boolean value

Integer(i64)

Integer value

Float(f64)

Floating point value

String value

Enum(String)

Enumeration value (.VALUE.)

List(Vec<AttributeValue>)

Implementations

impl AttributeValue

pub fn as_entity_ref(&self) -> Option<EntityId>

Try to get as entity reference

pub fn as_string(&self) -> Option<&str>

Try to get as string

pub fn as_float(&self) -> Option<f64>

Try to get as float

pub fn as_integer(&self) -> Option<i64>

Try to get as integer

pub fn as_bool(&self) -> Option<bool>

Try to get as boolean

pub fn as_enum(&self) -> Option<&str>

Try to get as enum string

pub fn as_list(&self) -> Option<&[AttributeValue]>

Try to get as list

pub fn is_null(&self) -> bool

Check if this is a null value

pub fn is_derived(&self) -> bool

Check if this is a derived value

Trait Implementations

impl Clone for AttributeValue

fn clone(&self) -> AttributeValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeValue

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

Formats the value using the given formatter.

impl Default for AttributeValue

fn default() -> AttributeValue

Returns the “default value” for a type.

impl PartialEq for AttributeValue

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