source ·
pub struct Accessor<'a> { /* private fields */ }
Expand description

A typed view into a buffer view.

Implementations§

source§

impl<'a> Accessor<'a>

source

pub fn index(&self) -> usize

Returns the internal JSON index.

source

pub fn size(&self) -> usize

Returns the size of each component that this accessor describes.

source

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.

source

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.

source

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.

source

pub fn data_type(&self) -> DataType

Returns the data type of components in the attribute.

source

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

Returns extension data unknown to this crate version.

source

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

Queries extension data unknown to this crate version.

source

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

Optional application specific data.

source

pub fn dimensions(&self) -> Dimensions

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

source

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

Returns the minimum value of each component in this attribute.

source

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

Returns the maximum value of each component in this attribute.

source

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

Optional user-defined name for this object.

source

pub fn normalized(&self) -> bool

Specifies whether integer data values should be normalized.

source

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

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