Enum toql_core::page::Page

pub enum Page {
    Uncounted(u64, u16),
    Counted(u64, u16),
}

It tells Toql to build and run an additional query to count the total number of records.

In Toql there are 2 types of counts: A filtered count and a total count. Lets take a datagrid where the user searches his contacts with a name starting with ‘Alice’. The datagrid would show the following:

• Total number of contacts (Unfiltered count)
• Number of found contacts with the name ‘Alice’ (Filtered count)

While the filtered count is almost for free and returned for every query, the total count needs a seperate query with a different SQL filter predicate. Toql can do that out of the box, but the fields must be mapped accordingly in the TableMapper

Variants

Uncounted(u64, u16)

Retrieve filtered count only. Argments are start index and number of records.

Counted(u64, u16)

Argments are start index and number of records.
