Implementations

impl DataType

pub fn comparison_numeric_coercion( l: &DataType, r: &DataType, ) -> QuillSQLResult<DataType>

Coerce lhs_type and rhs_type to a common type for the purposes of a comparison operation where one both are numeric

Trait Implementations

impl Clone for DataType

fn clone(&self) -> DataType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DataType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&DataType> for DataType

fn from(value: &DataType) -> Self

Converts to this type from the input type.

impl PartialEq for DataType

fn eq(&self, other: &DataType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&DataType> for DataType

type Error = QuillSQLError

The type returned in the event of a conversion error.

fn try_from(value: &DataType) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for DataType

type Error = QuillSQLError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for DataType

impl Eq for DataType

impl StructuralPartialEq for DataType
