Struct QueryRows 

pub struct QueryRows { /* private fields */ }

Schema-bearing result rows backed by immutable contiguous row buffers.

Implementations

impl QueryRows

pub fn empty() -> Self

pub fn schema(&self) -> &QuerySchema

pub fn iter(&self) -> QueryRowsIter<'_>

pub fn retain(&mut self, keep: impl FnMut(QueryRowRef<'_>) -> bool)
