Struct dae_parser::Unit

pub struct Unit {
    pub name: Option<String>,
    pub meter: f32,
}

Defines unit of distance for COLLADA elements and objects. This unit of distance applies to all spatial measurements within the scope of Asset’s parent element, unless overridden by a more local Asset / Unit.

The value of the unit is self-describing and does not have to be consistent with any real-world measurement.

Fields

name: Option<String>

The name of the distance unit. For example, “meter”, “centimeter”, “inches”, or “parsec”. This can be the real name of a measurement, or an imaginary name.

meter: f32

How many real-world meters in one distance unit as a floating-point number. For example, 1.0 for the name “meter”; 1000 for the name “kilometer”; 0.3048 for the name “foot”.

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Unit

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

Formats the value using the given formatter.

impl Default for Unit

fn default() -> Self

Returns the “default value” for a type.

impl XNode for Unit

const NAME: &'static str

The name of the XML element.

fn parse(element: &Element) -> Result<Self, Error>

Parse an XML element into this type. In most cases, the parser will require with a debug_assert that the element to parse has name Self::NAME.

fn parse_box(element: &Element) -> Result<Box<Self>, Error>

Parse an XML element and return the data structure in a Box. This can be faster in some cases when the data structure is large.

fn parse_one<'a>(
    it: &mut impl Iterator<Item = &'a Element>
) -> Result<Self, Error>

Parse a single required element from the given element iterator.

fn parse_opt(it: &mut Peekable<Children<'_>>) -> Result<Option<Self>, Error>

Parse an optional element from the given element iterator, using Self::NAME to determine if it is the correct type.

fn parse_opt_box(
    it: &mut Peekable<Children<'_>>
) -> Result<Option<Box<Self>>, Error>

Parse an optional boxed element from the given element iterator, using Self::NAME to determine if it is the correct type.

fn parse_list(it: &mut Peekable<Children<'_>>) -> Result<Vec<Self>, Error>

Parse a list of elements from the given element iterator, as long as it continues yielding elements of name Self::NAME.

fn parse_list_n<const N: usize>(
    it: &mut Peekable<Children<'_>>
) -> Result<Vec<Self>, Error>

Parse a list of elements from the given element iterator, as long as it continues yielding elements of name Self::NAME, and assert that the resulting list has length at least N.
