Module rmp::decode

Provides various functions and structs for MessagePack decoding.

Most of the function defined in this module will silently handle interruption error (EINTR) received from the given Read to be in consistent state with the Write::write_all method in the standard library.

Any other error would immediately interrupt the parsing process. If your reader can results in I/O error and simultaneously be a recoverable state (for example, when reading from non-blocking socket and it returns EWOULDBLOCK) be sure that you buffer the data externally to avoid data loss (using BufRead readers with manual consuming or some other way).
