Trait rubbl_core::num::DimFromShapeSlice

pub trait DimFromShapeSlice<T>: Sized {
    fn from_shape_slice(shape: &[T]) -> Result<Self, DimensionMismatchError>;
}

Adapt a slice representing an array shape into an ndarray::Dimension type.

In ndarray array dimensionalities are statically typed, but it is often the case that we are reading arrays from data files where the array dimensionality may not match the expectations of the compiled code. This trait makes it possible to convert a runtime-flexible array shape into one of the compile-time types … if the two dimensionalities are in fact the same.

Required methods

fn from_shape_slice(shape: &[T]) -> Result<Self, DimensionMismatchError>

Try to create the implementing type from the specified array shape, specified as a slice.

Returns an Err with an ErrorKind of DimensionMismatch if the slice size does not match the expected dimensionality.
