Struct Read 

pub struct Read<'a> {
    pub group: &'a [u8],
    pub consumer: &'a [u8],
    pub from: From,
    pub count: Option<usize>,
    pub noack: bool,
}

Everything XREADGROUP takes past the key.

A struct for the same reason Claim is one, and because the wire parses GROUP g c, COUNT n and NOACK in any order and would otherwise be carrying five loose values from the parse to the call.

Fields

group: &'a [u8]

Which group is reading.

consumer: &'a [u8]

Which consumer inside it, created by turning up if it is new.

from: From

> or an ID, which are two quite different commands wearing one name.

count: Option<usize>

COUNT, or everything there is.

noack: bool

NOACK, which hands the entries over without writing them down.
