Available on crate feature encoder only.

Attribute metadata produced by a successful mesh encode.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

source_attribute_id: i32

Source attribute id in the input mesh.

attribute_type: GeometryAttributeType

Semantic type of the encoded attribute.

data_type: DataType

Scalar data type of the encoded attribute.

num_components: u8

Number of scalar components per encoded value.

normalized: bool

Whether integer values are normalized.

unique_id: u32

Draco unique id assigned to the attribute.

num_encoded_values: usize

Number of unique values encoded for the attribute.

encoder_type: SequentialAttributeEncoderType

Per-attribute encoder the values went through, which is what decides whether the two fields below are populated.

quantization_bits: Option<i32>

Quantization bits applied, or None when the attribute was not quantized. A quantization_bits option set on an integer or generic attribute is ignored by the encoder and reported as None here.

prediction: Option<(PredictionSchemeMethod, PredictionSchemeTransformType)>

Prediction scheme and transform the encoder settled on, or None when the attribute never reached the integer path. This is the resolved choice, not the request: several schemes fall back to Difference when the attribute or the mesh cannot support them.

position_min: Option<Vec<f64>>

Minimum position components when known for position attributes.

position_max: Option<Vec<f64>>

Maximum position components when known for position attributes.
