pub struct Column {
pub name: String,
pub kind: String,
}Expand description
One result column: its name, and what the values under it turned out to be.
Fields§
§name: StringThe name the statement gave it.
kind: StringThe storage class of its values.
Observed, not declared, and the word is chosen for that. SQLite’s
typing is dynamic, so a column’s declared affinity is a hint about what
it will store rather than a fact about what it did. This is the fact:
the class every non-null value in the result actually had, mixed when
they disagreed and null when there were none.
