Expand description
The Error
enum indicates that something went wrong
It has 6 variants:
MissingHeader
that a header that is expected to be found was completely missing. There are some headers that are required everywhere in SIP, likeFrom
,To
etc.InvalidParam
means some header parser did not succeed, and the reason for it is a missing or invalid parameter. InnerString
should have the nom verbose error about it.ParseError
indicates a general parsing error. InnerString
should have the verbose nom error giving hints on what went wrong.TokenizeError
indicates a general tokenizer error. InnerString
should have the verbose nom error giving hints on what went wrong. A Tokenizer just tries to break thebytes
into parts/components of rsip structs, but never tries to parse/convert to a specific type. So if a tokenizer fails and you get this error, it means it couldn’t even manage to break the SIP message in the correct breakpoints.Utf8Error
indicates that thefrom_utf8
std method completely failed. At least you should get the information regarding which header had this issue.Unexpected
indicates any other error.
