Implementations

impl Affinity

pub fn of(declared_type: Option<&str>) -> Affinity

Apply the five rules to a declared type. A column declared without a type has blob affinity, which is the one that converts nothing.

pub fn as_str(self) -> &'static str

pub fn logical_class(self, value: &SqliteValue) -> StorageClass

What a stored value means once this column’s affinity is applied.

The only case where this differs from the physical class is an integer in a real affinity column, which is a float that SQLite wrote out compactly, and which SQLite itself reports as a real.
