Struct ValueShape 

pub struct ValueShape { /* private fields */ }
Description

Exact, storage-independent shape of one mathematical value.

Extents are ordered and positive. The empty extent list denotes a scalar, so a one-component vector ([1]) remains distinct from a scalar ([]). This type describes mathematical components only: mesh entities, basis functions, quadrature points, and memory strides belong to realization.

Implementations§

§

impl ValueShape

Signature links:§ValueShape

pub fn scalar() -> ValueShape

Signature links:scalarValueShape

Construct the scalar shape [].

pub fn new( extents: impl IntoIterator<Item = u32>, ) -> Result<ValueShape, InvalidValueShape>

Signature links:newIntoIteratoru32ResultValueShapeInvalidValueShape

Construct an exact tensor shape from positive portable extents.

§Errors

Returns InvalidValueShape at the first zero extent.

pub fn extents(&self) -> &[NonZero<u32>]

Signature links:extentsNonZerou32

Ordered canonical extents. An empty slice denotes a scalar.

pub const fn rank(&self) -> usize

Signature links:rankusize

Number of tensor axes.

pub const fn is_scalar(&self) -> bool

Signature links:is_scalarbool

Whether this is the exact scalar shape [].

pub fn component_count(&self) -> Option<usize>

Signature links:component_countOptionusize

Number of scalar components, when representable on this target.

A scalar has one component. This is value shape only; callers must separately account for spatial or temporal discretization cardinality.

pub fn appended(&self, extent: u32) -> Result<ValueShape, InvalidValueShape>

Signature links:appendedu32ResultValueShapeInvalidValueShape

Append one positive extent while preserving exact axis order.

§Errors

Returns InvalidValueShape when extent is zero.

pub fn remove_last(&self) -> Option<(ValueShape, NonZero<u32>)>

Signature links:remove_lastOptionValueShapeNonZerou32

Remove and return the trailing extent.

A scalar has no trailing extent and therefore returns None.
