Enum Opcode 

#[repr(C)]
pub enum Opcode {
    Register = 0,
    Lookup = 1,
    AuthenticatedLookup = 2,
    Unregister = 3,
    Disconnect = 4,
    TrustedInitDone = 5,
    BlockingConnect = 6,
    TryConnect = 7,
}

Variants

Register = 0

Create a new server with the given name and return its SID.

Lookup = 1

Create a connection to the target server.

AuthenticatedLookup = 2

Create an authenticated connection to the target server.

Unregister = 3

unregister a server, given its cryptographically unique SID.

Disconnect = 4

disconnect, given a server name and a cryptographically unique, one-time use token

TrustedInitDone = 5

indicates if all inherently trusted slots have been occupied. Should not run untrusted code until this is the case.

BlockingConnect = 6

Connect to a Server, blocking if the Server does not exist. When the Server is started, return with either the CID or an AuthenticationRequest

Message Types

* MutableLend

Arguments

The memory being pointed to should be a &str, and the length of the string should be specified in the valid field.

Return Values

Memory is overwritten to contain a return value. This return value can be defined as the following enum:

#[repr(C)]
#[non_exhaustive]
enum ConnectResult {
    Success(xous::CID /* connection ID */, [u32; 4] /* Disconnection token */),
    Error(u32 /* error code */),
    Unhandled, /* Catchall for future Results */
}

TryConnect = 7

Connect to a Server, returning the connection ID or an authentication request if it exists, and returning ServerNotFound if it does not exist.
