Struct basex::Connection [−][src]
pub struct Connection<T, State = Unauthenticated> where
T: DatabaseStream, {
state: PhantomData<State>,
stream: T,
}
Expand description
Responsible for low-level communication with the stream. It handles authentication, sends commands and reads responses.
As opposed to the Client
or Query
can do, connection does not understand what commands do or how to parse
responses. It can only send them, send arguments and be read like a stream.
Fields
state: PhantomData<State>
stream: T
Implementations
Creates a connection that communicates with the database via the provided stream
.
Authenticates the connection using the server protocol. Being authenticated is the pre-requisite for every other method to work.
Arguments
user
: Username.password
: Password.
Gets response string, and returns string if command was successful. Returns CommandFailed
error with a message otherwise.
