1//! # sparse-ir-dlr
2//!
3//! The discrete Lehmann representation (DLR), built independently of an IR
4//! basis by an interpolative decomposition of the logistic kernel (Kaye,
5//! Chen, Parcollet, PRB 105, 235115), with its interpolation nodes and the
6//! single-pole Green's functions.
7//!
8//! A DLR built from an IR basis (`DlrFromIr`) and the IR <-> DLR transform
9//! live in `sparse-ir-basis`. Most users depend on the `sparse-ir` crate.
