Backend-explicit preallocated-output einsum methods for TensorRead inputs.

Required Methods

fn einsum_read_into<B: TensorBackend>( &self, subscripts: &str, backend: &mut B, out: TensorWrite<'_>, ) -> Result<()>

Execute an einsum from string notation over read-only inputs into caller-provided 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_read_into_subscripts<B: TensorBackend>( &self, subscripts: &EinsumSubscripts, backend: &mut B, out: TensorWrite<'_>, ) -> Result<()>

Execute an einsum from parsed integer-label subscripts over read-only inputs into 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", so this trait is not object safe.
