nab-provider
Apply Python packaging rules during dependency resolution. This package supplies candidate versions
and their dependency constraints to nab-resolver,
including environment markers and build, distribution, and VCS policies.
It performs no networking, file access, or subprocess calls.
Package listings and metadata arrive through nab_provider.fetch_port.FetchPort, an interface
implemented by the application using the provider. That application is called the host;
nab-project supplies it for the nab CLI. nab_provider.testing supplies an in-memory
implementation for tests.
When to use it
Use nab-provider to embed nab's resolution in a host that already owns its networking and caching,
keeping nab-index out of the import graph. Most users want
nab instead.
The API is currently under rapid experimentation, if you use it pin to an exact version.
