Enum Entry 

pub enum Entry<'a> {
    Int(i64),
    Str(&'a [u8]),
}

One element, as it is stored.

Redis stores a member that looks like an integer as an integer, so SADD s 1 and SADD s 01 are two different members that are stored two different ways. Handing back which one it was is what lets a caller answer OBJECT ENCODING and write an RDB without re-deciding it.

Variants

Int(i64)

Stored as an integer, in one of the six integer encodings.

Str(&'a [u8])

Stored as bytes.

Implementations

impl Entry<'_>

pub fn write_to(&self, out: &mut Vec<u8>)

The element as a client would see it, appended to out.

An integer entry is formatted here, which is the same round trip Redis does on the way out, because the client asked for a member and members are strings on the wire.

pub fn byte_len(&self) -> usize

How many bytes a client would see, without formatting anything.

This is HSTRLEN and STRLEN, which both have to answer for a value stored as an integer, and neither of them should have to write the digits out to count them.

pub fn to_vec(&self) -> Vec<u8>

The element as bytes, allocating only for an integer.
