Struct VariableShapeTensorMetadata

pub struct VariableShapeTensorMetadata {
    dim_names: Option<Vec<String>>,
    permutations: Option<Vec<usize>>,
    uniform_shape: Option<Vec<Option<i32>>>,
}

Extension type metadata for VariableShapeTensor.

Fields

dim_names: Option<Vec<String>>

Explicit names to tensor dimensions.

permutations: Option<Vec<usize>>

Indices of the desired ordering of the original dimensions.

uniform_shape: Option<Vec<Option<i32>>>

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

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>

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]>

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

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

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

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

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

fn clone(&self) -> VariableShapeTensorMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VariableShapeTensorMetadata

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

Formats the value using the given formatter.

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

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

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
