Trait Implementations

impl Clone for LogicalType

fn clone(&self) -> LogicalType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LogicalType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LogicalType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LogicalType

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

Formats the value using the given formatter.

impl Hash for LogicalType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LogicalType

fn cmp(&self, other: &LogicalType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LogicalType

fn eq(&self, other: &LogicalType) -> 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 PartialOrd for LogicalType

fn partial_cmp(&self, other: &LogicalType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ReferenceSerialization for LogicalType

fn encode<W: Write>( &self, writer: &mut W, is_direct: bool, reference_tables: &mut ReferenceTables, ) -> Result<(), DatabaseError>

fn decode<T: Transaction, R: Read>( reader: &mut R, drive: Option<(&T, &SharedLruCache<TableName, TableCatalog>)>, reference_tables: &ReferenceTables, ) -> Result<Self, DatabaseError>

impl Serialize for LogicalType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<DataType> for LogicalType

sqlparser datatype to logical type

type Error = DatabaseError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl Eq for LogicalType

impl StructuralPartialEq for LogicalType
