Struct pasture_core::layout::PointAttributeDefinition

pub struct PointAttributeDefinition { /* private fields */ }

A definition for a single point attribute of a point cloud. Point attributes are things like the position, GPS time, intensity etc. In Pasture, attributes are identified by a unique name together with the data type that a single record of the attribute is stored in. Attributes can be grouped into two categories: Built-in attributes (e.g. POSITION_3D, INTENSITY, GPS_TIME etc.) and custom attributes.

Implementations

impl PointAttributeDefinition

pub const fn custom( name: Cow<'static, str>, datatype: PointAttributeDataType, ) -> Self

Creates a new custom PointAttributeDefinition with the given name and data type

let custom_attribute = PointAttributeDefinition::custom(Cow::Borrowed("Custom"), PointAttributeDataType::F32);

pub fn name(&self) -> &str

Returns the name of this PointAttributeDefinition

let custom_attribute = PointAttributeDefinition::custom(Cow::Borrowed("Custom"), PointAttributeDataType::F32);
let name = custom_attribute.name();

pub const fn datatype(&self) -> PointAttributeDataType

Returns the datatype of this PointAttributeDefinition

let custom_attribute = PointAttributeDefinition::custom(Cow::Borrowed("Custom"), PointAttributeDataType::F32);
let datatype = custom_attribute.datatype();

pub const fn size(&self) -> u64

Returns the size in bytes of this attribute

pub fn with_custom_datatype(&self, new_datatype: PointAttributeDataType) -> Self

Returns a new PointAttributeDefinition based on this PointAttributeDefinition, but with a different datatype

let custom_position_attribute = attributes::POSITION_3D.with_custom_datatype(PointAttributeDataType::Vec3f32);

pub fn at_offset_in_type(&self, offset: u64) -> PointAttributeMember

Creates a PointAttributeMember from the associated PointAttributeDefinition by specifying an offset of the attribute within a PointType. This turns an abstract PointAttributeDefinition into a concrete PointAttributeMember

let custom_position_attribute = attributes::POSITION_3D.at_offset_in_type(8);

Trait Implementations

impl Clone for PointAttributeDefinition

fn clone(&self) -> PointAttributeDefinition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PointAttributeDefinition

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

Formats the value using the given formatter.

impl Display for PointAttributeDefinition

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

Formats the value using the given formatter.

impl FromIterator<PointAttributeDefinition> for PointLayout

fn from_iter<T: IntoIterator<Item = PointAttributeDefinition>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for PointAttributeDefinition

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 PointAttributeDefinition

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

This method tests for self and other values to be equal, and is used by ==.

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

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