StreamItem

Enum StreamItem 

Source
pub enum StreamItem<'a> {
    Header(&'a [ColumnSchema]),
    Row(&'a [&'a Value]),
}
Expand description

v7.37 — one item in the streaming SELECT emit channel. The engine yields exactly one Header (before any row) then zero or more Rows. Pgwire (or any other consumer) decides how to turn those into wire bytes.

Variants§

§

Header(&'a [ColumnSchema])

§

Row(&'a [&'a Value])
