The aim of the wrapt module is to provide a transparent object proxy
|
|
for Python, which can be used as the basis for the construction of
|
|
function wrappers and decorator functions.
|
|
|
|
The wrapt module focuses very much on correctness. It therefore
|
|
goes way beyond existing mechanisms such as functools.wraps() to
|
|
ensure that decorators preserve introspectability, signatures, type
|
|
checking abilities etc. The decorators that can be constructed using
|
|
this module will work in far more scenarios than typical decorators
|
|
and provide more predictable and consistent behaviour.
|
|
|
|
To ensure that the overhead is as minimal as possible, a C extension
|
|
module is used for performance critical components. An automatic
|
|
fallback to a pure Python implementation is also provided where a
|
|
target system does not have a compiler to allow the C extension to
|
|
be compiled.
