Enum PyroType 

pub enum PyroType<'a> {
    Null,
    PrimitiveScalar(PrimitiveDataType),
    Str,
    Timestamp,
    PrimitiveList(PrimitiveDataType),
    PrimitiveFixedList(PrimitiveDataType, usize),
    List(Box<PyroType<'a>>, bool),
    Group(Cow<'a, [PyroField<'a>]>),
    Map {
        key: Box<PyroType<'a>>,
        value: Box<PyroType<'a>>,
    },
}

A data type enum that mirrors the variants of [PyroValue] exactly.

This is intentionally much smaller than arrow::datatypes::DataType. Every variant here has a 1:1 correspondence with a PyroValue discriminant.

Variants

Null

No value / unknown type (corresponds to PyroValue::Null).

PrimitiveScalar(PrimitiveDataType)

Scalar primitive (Bool, Int, Float).

Str

UTF-8 string (corresponds to PyroValue::Str).

Timestamp

Day + millisecond interval (corresponds to PyroValue::Timestamp).

PrimitiveList(PrimitiveDataType)

Homogeneous list of a single primitive type (corresponds to PyroValue::PrimitiveList).

PrimitiveFixedList(PrimitiveDataType, usize)

Fixed-size homogeneous list of a single primitive type.

List(Box<PyroType<'a>>, bool)

Heterogeneous list of arbitrary pyro values (corresponds to PyroValue::List).

Fields: (element_type, element_nullable).

Group(Cow<'a, [PyroField<'a>]>)

Named struct / row (corresponds to PyroValue::Group).

Map

Key-value map (corresponds to PyroValue::MapInternal).

Fields

key: Box<PyroType<'a>>

value: Box<PyroType<'a>>

Implementations

impl<'a> PyroType<'a>

pub fn into_owned(self) -> PyroType<'static>

Trait Implementations

impl<'a> Clone for PyroType<'a>

fn clone(&self) -> PyroType<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PyroType<'a>

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

Formats the value using the given formatter.

impl<'de, 'a> Deserialize<'de> for PyroType<'a>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Display for PyroType<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for PyroType<'a>

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<'a> PartialEq for PyroType<'a>

fn eq(&self, other: &PyroType<'a>) -> 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<'a> Serialize for PyroType<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
