numcodecs_observers

Observe encoding and decoding in the numcodecs buffer compression API.

The following observers, implementing the CodecObserver class are provided:

• BytesizeObserver: measure the byte size of the data before and after encoding / decoding
• WalltimeObserver: measure the walltime it takes to encode / decode

Modules:

• abc –

  This module defines the CodecObserver base class, which allows observing a Codec's encode and decode calls.

• bytesize –

  This module defines the BytesizeObserver class, which measures the byte size of the data before and after encoding / decoding.

• hash –

  This module defines the HashableCodec helper class, which wraps an existing Codec and makes it hashable.

• walltime –

  This module defines the WalltimeObserver class, which measures the walltime it takes to encode / decode.

Functions:

• observe –

  Context manager to wrap the provided codec such that the observers

observe(codec: Codec, observers: Sequence[CodecObserver])
