//! rust-analyzer is lazy and doesn't not compute anything unless asked. This

//! sometimes is counter productive when, for example, the first goto definition

//! request takes longer to compute. This modules implemented prepopulating of
|
|
//! various caches, it's not really advanced at the moment.
