1 Clients
Each client represents a single TCP connection to the Redis server.
procedure
(make-redis [ #:client-name client-name #:host host #:port port #:timeout timeout #:db db #:password password]) → redis? client-name : string? = "racket-redis" host : string? = "127.0.0.1" port : (integer-in 0 65536) = 6379 timeout : exact-nonnegative-integer? = 5 db : (integer-in 0 16) = 0 password : (or/c false/c non-empty-string?) = #f
Creates a Redis client and immediately attempts to connect to the
database at host and port. The timeout
parameter controls the maximum amount of time (in milliseconds) the
client will wait for any individual response from the database.
Each client maps to an individual connection, therefore clients are not thread safe! See Connection Pooling.
Returns #t when v is a Redis client.
procedure
(redis-connected? client) → boolean?
client : redis?
Returns #t when client appears to be connected to
the database. Does not detect broken pipes.
procedure
(redis-connect! client) → void?
client : redis?
Initiates a connection to the database. If one is already open,
then the client is first disconnected before the new connection is
made.
procedure
(redis-disconnect! client) → void?
client : redis?
Disconnects from the server immediately and without sending a
QUIT command. Does nothing if the client is already
disconnected.
value
redis-key/c : (or/c bytes? string?)
The contract for valid Redis keys.
value
redis-key-type/c : (or/c 'string 'list 'set 'zset 'hash 'stream)
The contract for valid Redis key types.
value
The contract for valid Redis byte strings. Anywhere you see this
contract, keep in mind that any string value you provide will be
converted to bytes? via string->bytes/utf-8.
value
: (or/c false/c bytes? exact-integer? (listof redis-value/c))
The contract for Redis response values.
