Struct dae_parser::Input

pub struct Input {
    pub semantic: Semantic,
    pub source: Url,
}

Declares the input semantics of a data source and connects a consumer to that source. In the COLLADA spec this is called “<input> (unshared)”.

Fields

semantic: Semantic

The user-defined meaning of the input connection.

source: Url

The location of the data source. The type referenced here depends on the semantic:

• For Semantic::Vertex it references a Vertices
• For most other semantics it references a Source

Implementations

impl Input

pub fn source_as_source(&self) -> &UrlRef<Source>

Typecast self.source as a UrlRef<Source>. The semantic is checked in debug mode to ensure that it is compatible with a Source target.

pub fn source_as_vertices(&self) -> &UrlRef<Vertices>

Typecast self.source as a UrlRef<Vertices>. The semantic is checked in debug mode to ensure that it is compatible with a Vertices target.

Trait Implementations

impl Clone for Input

fn clone(&self) -> Input

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Input

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

Formats the value using the given formatter.

impl XNode for Input

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.
