Enum redust_resp::Data

pub enum Data<'a> {
    SimpleString(Cow<'a, str>),
    Integer(i64),
    BulkString(Cow<'a, [u8]>),
    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(Cow<'a, str>)

Integer(i64)

BulkString(Cow<'a, [u8]>)

Array(Vec<Data<'a>>)

Null
