Enum Data 

pub enum Data<'a> {
    SimpleString(HipStr<'a>),
    Integer(i64),
    BulkString(Bulk<'a>),
    Array(Vec<Data<'a>>),
    Null,
}

RESP data. Read the Redis documenation for details on which type to expect as a response.

Both Data::BulkString and Data::Array can represent nulls in RESP, but in this representation they are not optional. They will be represented with Data::Null if the bulk string or array is null.

Errors are not represented here for two reasons: 1) it’s never correct to send an error to the Redis server, and 2) it’s more ergonomic to have errors returned in a Result.

Since errors are not represented, it’s possible to convert a Rust string into Data without ambiguity.

Variants

SimpleString(HipStr<'a>)

Integer(i64)

BulkString(Bulk<'a>)

Array(Vec<Data<'a>>)

Null
