Expand description

Anything that implements this trait can directly add itself to the bytes part of a Query object

Implementing this trait

This trait does not need to be implemented manually for some basic objects. Once you implement IntoSkyhashBytes, it is implemented automatically. This trait will need to be implemented manually for other objects however. For example:

use skytable::types::IntoSkyhashAction;
use skytable::Query;

struct MyVecWrapper(Vec<String>);

impl IntoSkyhashAction for MyVecWrapper {
    fn push_into_query(&self, q: &mut Query) {
        self.0.iter().for_each(|element| q.push(element));
    }
    fn incr_len_by(&self) -> usize {
        self.0.len()
    }
}

Unexpected behavior

As you can see, it is easy enough for someone to miss an element while implementing (maybe not the best example) IntoSkyhashAction::push_into_query() and also misguide the client driver about the length in the implementation for IntoSkyhashAction::incr_len_by(). This is why you should stay on the guard while implementing it.

Required methods

Extend the bytes of a Vec of bytes

Returns the number of items Self will add to the query
