GridRequest

Struct GridRequest 

Source
#[non_exhaustive]
pub struct GridRequest { pub offset: usize, pub limit: usize, pub sort: Vec<(usize, SortDirection)>, pub filters: Vec<String>, pub search: String, pub after: Option<Row>, pub wants_total: bool, }
Expand description

What a RemoteRows loader must bring.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§offset: usize

The first row wanted, from the start of the result.

§limit: usize

How many rows, at most.

§sort: Vec<(usize, SortDirection)>

Sort columns (zero-based) in priority order.

§filters: Vec<String>

Filter text per column (index = column).

§search: String

What is being searched for.

§after: Option<Row>

The row just before offset, when it is at hand. With it a query can continue from there (WHERE key > ?) and not walk past offset rows, which is what makes OFFSET slow on a big table.

§wants_total: bool

Whether the total is still unknown. Answer None to leave it so: a total can cost the database more than all the rows ever shown.
