Struct Spec 

pub struct Spec {
    pub name: &'static str,
    pub arity: i32,
    pub flags: &'static [&'static str],
    pub first_key: i32,
    pub last_key: i32,
    pub step: i32,
    pub acl: &'static [&'static str],
    pub since: &'static str,
    pub complexity: &'static str,
    pub summary: &'static str,
    pub group: &'static str,
    pub keys: &'static [KeySpec],
}

Everything COMMAND has to be able to say about one command.

Fields

name: &'static str

The name, lower case, which is how COMMAND reports it whatever case the client used.

arity: i32

Redis’s arity: a positive number is exact, a negative one is a minimum of its magnitude, and both count the command name itself.

flags: &'static [&'static str]

The command flags, in the order COMMAND INFO lists them.

first_key: i32

The first argument that is a key, or zero when there are none.

last_key: i32

The last argument that is a key, negative counting back from the end.

step: i32

How far apart the keys are, for the commands that take pairs.

acl: &'static [&'static str]

The ACL categories, which are what COMMAND LIST FILTERBY ACLCAT reads.

A container row carries only what the container itself is in, which is what a real server reports for it. The categories its subcommands add on top are in SUBCATS.

since: &'static str

The Redis this command first appeared in.

complexity: &'static str

The cost, in the shape COMMAND DOCS uses.

summary: &'static str

One line about what it does, in our words.

group: &'static str

The group in commands.toml, which is how the two files are compared.

keys: &'static [KeySpec]

Where this command’s keys are and what it does to each of them.

The triple above is Redis’s legacy answer and is kept because COMMAND INFO still reports it. This is the one that is right, and it is the one the ACL reads. See the keyspec module for what the difference costs.
