Ferricstore.Commands.Dispatcher (ferricstore v0.4.2)

Routes Redis command names to the appropriate handler module.

The dispatcher normalises the command name to uppercase and delegates to one of:

Ferricstore.Commands.Strings — GET, SET, DEL, EXISTS, MGET, MSET, INCR, DECR, INCRBY, DECRBY, INCRBYFLOAT, APPEND, STRLEN, GETSET, GETDEL, GETEX, SETNX, SETEX, PSETEX, GETRANGE, SETRANGE, MSETNX
Ferricstore.Commands.Expiry — EXPIRE, PEXPIRE, EXPIREAT, PEXPIREAT, TTL, PTTL, PERSIST
Ferricstore.Commands.Generic — TYPE, UNLINK, RENAME, RENAMENX, COPY, RANDOMKEY, SCAN, EXPIRETIME, PEXPIRETIME, OBJECT, WAIT
Ferricstore.Commands.Server — PING, ECHO, DBSIZE, KEYS, FLUSHDB, FLUSHALL, INFO, COMMAND, SELECT, LOLWUT, DEBUG

Multi-word commands (CLIENT, COMMAND) are routed based on the first word, then the subcommand is extracted from args. CLIENT subcommands require connection state and are dispatched via dispatch_client/3.

Unknown commands return {:error, "ERR unknown command ..."}.
