Struct Accessor

pub struct Accessor<'a> { /* private fields */ }

A typed view into a buffer view.

Implementations

impl<'a> Accessor<'a>

pub fn index(&self) -> usize

Returns the internal JSON index.

pub fn size(&self) -> usize

Returns the size of each component that this accessor describes.

pub fn view(&self) -> Option<View<'a>>

Returns the buffer view this accessor reads from.

This may be None if the corresponding accessor is sparse.

pub fn offset(&self) -> usize

Returns the offset relative to the start of the parent buffer view in bytes.

This will be 0 if the corresponding accessor is sparse.

pub fn count(&self) -> usize

Returns the number of components within the buffer view - not to be confused with the number of bytes in the buffer view.

pub fn data_type(&self) -> DataType

Returns the data type of components in the attribute.

pub fn extensions(&self) -> Option<&Map<String, Value>>

Available on crate feature extensions only.

Returns extension data unknown to this crate version.

pub fn extension_value(&self, ext_name: &str) -> Option<&Value>

Available on crate feature extensions only.

Queries extension data unknown to this crate version.

pub fn extras(&self) -> &'a Extras

Optional application specific data.

pub fn dimensions(&self) -> Dimensions

Specifies if the attribute is a scalar, vector, or matrix.

pub fn min(&self) -> Option<Value>

Returns the minimum value of each component in this attribute.

pub fn max(&self) -> Option<Value>

Returns the maximum value of each component in this attribute.

pub fn name(&self) -> Option<&'a str>

Available on crate feature names only.

Optional user-defined name for this object.

pub fn normalized(&self) -> bool

Specifies whether integer data values should be normalized.

pub fn sparse(&self) -> Option<Sparse<'a>>

Returns sparse storage of attributes that deviate from their initialization value.

Trait Implementations

impl<'a> Clone for Accessor<'a>

fn clone(&self) -> Accessor<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Accessor<'a>

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

Formats the value using the given formatter.
