Error propagation through codecs #11

Open clbarnes opened 1 year ago

clbarnes commented 1 year ago

Probably needs a CodecError enum which contains an "Other" type for potential future codec-specific errors. This could roll io::Error into it.

clbarnes commented 1 year ago

bytes -> bytes

all
- io::Error
blosc
- unavailable compressor or bad typesize (on writer construction)
gzip

array -> bytes

all
- io::Error
- anything from any other codec (because the codecchain itself is an AB codec)
endian
- endian type wrangling
- decoded repr data type mismatches generic array (decode)
sharding
- anything from any other codec
- bad chunk spec (e.g. does not exactly subdivide chunk)

array -> array

transpose
- invalid permutation (could just panic as we know the ones we construct are safe)
