TileCursor

Struct TileCursor 

Source
pub struct TileCursor<'a> { /* private fields */ }
Expand description

A prepared tile scan, owning its statement so that TileCursor::tiles can borrow each payload straight out of the row.

The split is the one crate::FeatureCursor uses, and for the same reason: rusqlite’s row cursor borrows its statement, so an iterator owning both would be self-referential, which #![forbid(unsafe_code)] rules out.

Implementations§

Source§

impl TileCursor<'_>

Source

pub fn tiles(&mut self) -> Result<TileStream<'_>>

Runs the scan and walks its tiles.

Each call re-runs the query from the start, so a cursor can be walked more than once.
