Struct VariableShapeTensorMetadata 

pub struct VariableShapeTensorMetadata { /* private fields */ }

Extension type metadata for VariableShapeTensor.

Implementations

impl VariableShapeTensorMetadata

pub fn try_new( dimensions: usize, dimension_names: Option<Vec<String>>, permutations: Option<Vec<usize>>, uniform_shapes: Option<Vec<Option<i32>>>, ) -> Result<Self, ArrowError>

Available on crate feature canonical_extension_types only.

Returns metadata for a variable shape tensor extension type.

Error

Return an error if the provided dimension names, permutations or uniform shapes are invalid.

pub fn dimension_names(&self) -> Option<&[String]>

Available on crate feature canonical_extension_types only.

Returns the names of the dimensions in this variable shape tensor, if set.

pub fn permutations(&self) -> Option<&[usize]>

Available on crate feature canonical_extension_types only.

Returns the indices of the desired ordering of the original dimensions, if set.

pub fn uniform_shapes(&self) -> Option<&[Option<i32>]>

Available on crate feature canonical_extension_types only.

Returns sizes of individual tensor’s dimensions which are guaranteed to stay constant in uniform dimensions and can vary in non-uniform dimensions.

Trait Implementations

impl Clone for VariableShapeTensorMetadata

Available on crate feature canonical_extension_types only.

fn clone(&self) -> VariableShapeTensorMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariableShapeTensorMetadata

Available on crate feature canonical_extension_types only.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VariableShapeTensorMetadata

Available on crate feature canonical_extension_types only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VariableShapeTensorMetadata

Available on crate feature canonical_extension_types only.

fn eq(&self, other: &VariableShapeTensorMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for VariableShapeTensorMetadata

Available on crate feature canonical_extension_types only.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
