Backend-explicit preallocated-output einsum methods for typed concrete tensors.

Required Methods

fn einsum_into<'out, O>( &self, subscripts: &str, session: &mut dyn BackendSession, out: O, ) -> Result<()>

where O: Into<TypedTensorWrite<'out, T>>,

Execute an einsum from string notation into caller-provided typed output.

Errors

Returns Error::InvalidSubscripts for malformed notation, Error::Validation with a shape, rank, or dtype payload when inputs or output do not match, or Error::Tensor for a typed backend failure.

fn einsum_into_notation<'out, O>( &self, notation: &EinsumNotation, session: &mut dyn BackendSession, out: O, ) -> Result<()>

where O: Into<TypedTensorWrite<'out, T>>,

Execute an einsum from rank-unresolved notation into typed output.

Examples

use tenferro_einsum::{EinsumAxis, EinsumNotation};
let notation = EinsumNotation::new(&[&[EinsumAxis::Ellipsis]], &[]);
assert_eq!(notation.input_count(), 1);

Errors

Returns a typed validation or backend error when notation, shapes, or output are invalid.

fn einsum_into_subscripts<'out, O>( &self, subscripts: &EinsumSubscripts, session: &mut dyn BackendSession, out: O, ) -> Result<()>

where O: Into<TypedTensorWrite<'out, T>>,

Execute an einsum from parsed integer-label subscripts into caller-provided typed output.

Errors

Returns Error::Validation with a shape, rank, or dtype payload when inputs or output do not match, or Error::Tensor for a typed backend failure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
