}

Logical data type representing user-facing type semantics. Multiple logical types may share the same PhysicalType (e.g., Date/Timestamp/TimestampNs all use Int64 physically).

Implementations

impl LogicalType

pub fn physical_type(&self) -> PhysicalType

Returns the physical storage type for this logical type.

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

Human-readable type name for error messages.

pub fn is_numeric(&self) -> bool

Whether this is a numeric type (integer or floating-point).

pub fn is_integer(&self) -> bool

Whether this is an integer type (signed or unsigned).

pub fn is_temporal(&self) -> bool

Whether this is a temporal type.

pub fn is_nested(&self) -> bool

Whether this is a nested type (List, Array, Struct, Map, Union).

Trait Implementations

impl Clone for LogicalType

fn clone(&self) -> LogicalType

Returns a duplicate 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 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 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 Eq for LogicalType

impl StructuralPartialEq for LogicalType
