gleamunison/cli_store

A CLI owns its store handle: errors are data, and every completed action closes before its result reaches the process-exit boundary.

Values

with_dets

</>

pub fn with_dets(
  path: String,
  run: fn(storage.StorageAdapter) -> Result(a, String),
) -> Result(a, String)

Open a store, run the action, close the store. Errors carry a String.

with_dets_mapped

</>

pub fn with_dets_mapped(
  path: String,
  run: fn(storage.StorageAdapter) -> Result(a, e),
  on_store_error: fn(String) -> e,
) -> Result(a, e)

Same lifecycle for a caller whose error type is richer than String — a CLI whose exit code is part of the contract, for instance. on_store_error lifts the store’s own failures into that type so one channel carries every failure.
