bitmap_commands.go:182–197

BitFieldRO - Read-only variant of the BITFIELD command. It is like the original BITFIELD but only accepts GET subcommand and can safely be used in read-only replicas. - BitFieldRO(ctx, key, " ", " ", " "," ")

(ctx context.Context, key string, values ...interface{})

// It is like the original BITFIELD but only accepts GET subcommand and can safely be used in read-only replicas.
