couch_lib
application is a collection of “pure” miscellaneous functions. They are “pure” in a sense that these functions should not call any other CouchDB applications. Think of this application as an extension for Erlang/OTP standard library.
The two main reasons for this application to exist are:
Please DO NOT put CouchDB specific functionality in here. This means you shouldn't:
erlang:put/2
gen_server
processes using gen_server:call
All string parsing functions expect either string or binary as well as the type itself. I.e. if parse_boolean/1
is called as parse_boolean(true)
it would return true
. They return either the parsed type or {error, Reason :: term()}
.
couch_lib_parse:parse_boolean/1
- parses given string or binary into Erlang's boolean()
typecouch_lib_parse:parse_integer/1
- parses given string as Erlang's integer()
typecouch_lib_parse:parse_non_neg_integer/1
- parses given string as Erlang's non_neg_integer()
type ([0..infinity)
