View Source Explorer.Backend (Explorer v0.4.0)
The behaviour for Explorer backends and associated functions.
Each backend is a module with DataFrame and Series submodules that match the
respective behaviours for each.
The default backend is read from the application environment. Currently, the only
backend is an in-memory, eager one based on
Polars. When alternatives are
available, you can use them by configuring your runtime:
# config/runtime.exs
import Config
config :explorer, default_backend: Lib.CustomBackendLink to this section Summary
Functions
Gets the default backend for the current process.
Sets the current process default backend to backend.
Link to this section Functions
Gets the default backend for the current process.
Sets the current process default backend to backend.
The default backend is stored only in the process dictionary. This means if
you start a separate process, such as Task, the default backend must be set
on the new process too.
