Implementations

impl Value

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

pub fn cmp_value(&self, other: &Value) -> Ordering

Total ordering used by comparisons and B-trees. NULL sorts lowest.

pub fn is_truthy(&self) -> Option<bool>

Truthiness per SQL-ish rules: nonzero numbers and their own values.

pub fn coerce_to(&self, ty: &ColumnType) -> Result<Value, String>
