Implementations§

Source§

impl RowValue

Source

pub fn from_scalar(s: ScalarValue) -> Self

Convert a primitive ScalarValue to a row value (for PK and v1 interop).

Source

pub fn as_scalar(&self) -> Option<ScalarValue>

If this row value is a primitive, return its scalar form (for PK encoding).

Source

pub fn into_scalar(self) -> Result<ScalarValue, DbError>

Require a primitive scalar (for get / PK lookup parameters).
