"""For neatly implementing static typing in pip.
|
||||
|
||||
`mypy` - the static type analysis tool we use - uses the `typing` module, which
|
||||
provides core functionality fundamental to mypy's functioning.
|
||||
|
||||
Generally, `typing` would be imported at runtime and used in that fashion -
|
||||
it acts as a no-op at runtime and does not have any run-time overhead by
|
||||
design.
|
||||
|
||||
As it turns out, `typing` is not vendorable - it uses separate sources for
|
||||
Python 2/Python 3. Thus, this codebase can not expect it to be present.
|
||||
To work around this, mypy allows the typing import to be behind a False-y
|
||||
optional to prevent it from running at runtime and type-comments can be used
|
||||
to remove the need for the types to be accessible directly during runtime.
|
||||
|
||||
This module provides the False-y guard in a nicely named fashion so that a
|
||||
curious maintainer can reach here to read this.
|
||||
|
||||
In pip, all static-typing related imports should be guarded as follows:
