Crate sparse_ir_core 

sparse-ir-core

The representation-independent layer of sparse-ir: statistics and Matsubara frequencies, the error type, GEMM dispatch, the least-squares fitters, the Basis trait, and sparse sampling in imaginary time and Matsubara frequency for any Basis.

Most users depend on the sparse-ir crate, which re-exports this crate together with the IR basis, the DLR and MiniPole.
