Command info result for the command command.

Fields

name: String

This is the command’s name in lowercase.

arity: isize

Arity is the number of arguments a command expects. It follows a simple pattern:

• A positive integer means a fixed number of arguments.
• A negative integer means a minimal number of arguments.

flags: Vec<String>

Command flags are an array. See COMMAND documentation for the list of flags

first_key: usize

The position of the command’s first key name argument. For most commands, the first key’s position is 1. Position 0 is always the command name itself.

last_key: isize

The position of the command’s last key name argument.

step: usize

The step, or increment, between the first key and the position of the next key.

acl_categories: Vec<String>

[From Redis 6.0] This is an array of simple strings that are the ACL categories to which the command belongs.

command_tips: Vec<CommandTip>

[From Redis 7.0] Helpful information about the command. To be used by clients/proxies. See https://redis.io/docs/reference/command-tips/

key_specifications: Vec<KeySpecification>

[From Redis 7.0] This is an array consisting of the command’s key specifications. See https://redis.io/docs/reference/key-specs/

sub_commands: Vec<CommandInfo>
