Issue with HSET command in Rust Redis

Question

I am currently trying to convert the following Redis command into rust:

HSET book_store_list 1 1,2,3

Essentially, create the bookstore_list Hash, with a Field (1) and value (1,2,3) which works fine within the Redis GUI.

The issue is that the hset API in rust redis does not seem to work as I envisioned.

For example:

let vector = vec![1,2,3]
hset("book_store_list", 1, &vector) 

Results in two Field-Value entries within the book_store_list hash

Field 1 Value 1 Field 2 Value 3

The issue is that the redis rust crate seems to interpret the [1,2,3] vector to be separate values (with 2 and 3 being a new field value pair) to be cached in instead of one value. Just wondering if anyone has faced this issue before?

Answer 1

Believe that I have found the answer. In order for Redis to accept [1,2,3] as one singular value, we must call the to_string api from the serde_json crate like so:

let value = serde_json::to_string(&vector).unwrap();

I guess the lesson of this is to stringify all values before invoking any HSET commands in rust redis!
