Struct Window 

pub struct Window {
    pub limit: i64,
    pub offset: i64,
}

A resolved window, clamped into something a query can be handed.

Fields

limit: i64

offset: i64

Implementations

impl Window

pub fn resolve(limit: i64, offset: i64) -> Self

Clamps a caller’s window rather than refusing it.

A --limit 0 or a negative offset is nonsense rather than an attack, and answering with the smallest usable page is more useful than an error; passed through to SQL, LIMIT -1 means no limit in SQLite, which is the one answer a window must never accidentally give.

Deliberately not clamped to admin.page_size_max: that key is a ceiling on what an HTTP caller may ask the server for, and this front end answers to a shell on the host. There is no upper bound on the offset either, unlike webadmin::handlers::paging, because nothing here computes offset + limit — a terminal has no “next page” link to place.
