module type TLS_EXCEPTIONS =sig..end
The exceptions the TLS provider may use (in addition to OCaml's built-in
exception). In Ocamlnet, these exceptions are actually defined in
Netsys_types.
exception EAGAIN_RD
exception EAGAIN_WR
A read or write cannot be done because the descriptor is in
non-blocking mode and would block. This corresponds to the
Unix.EAGAIN error but includes whether it was a read or write.
When the read or write is possible, the interrupted function should simply be again called.
These two exceptions are preferred by TLS providers.
exception TLS_switch_request
The server requested a rehandshake (this exception is thrown in the client)
exception TLS_switch_response of bool
The client accepted or denied a rehandshake (this exception is thrown
in the server). true means acceptance.
exception TLS_error of string
A fatal error occurred (i.e. the session needs to be terminated). The string is a symbol identifying the error.
exception TLS_warning of string
A non-fatal error occurred. The interrupted function should be called again. The string is a symbol identifying the warning.
