Implementations

impl ProtoFieldType

pub fn from_json_value(value: &Value) -> Self

pub fn from_avro_schema(schema: &Schema) -> Self

pub fn from_arrow_type(data_type: &ArrowDataType) -> Self

pub fn from_field_type(ftype: &ProstType) -> Self

pub fn can_widen_to(&self, other: &Self) -> bool

Widening chain: int32 -> int64 -> double -> string, float -> double -> string, bool/bytes/timestamp -> string.

pub fn wider_type(&self, other: &Self) -> Self

pub fn to_proto_type(&self) -> ProstType

pub fn to_delta_type_name(&self) -> &'static str

Delta/Spark SQL DDL type name.

pub fn to_uc_api_type_name(&self) -> &'static str

Unity Catalog REST API type name (POST /api/2.1/unity-catalog/tables)

Trait Implementations

impl Clone for ProtoFieldType

fn clone(&self) -> ProtoFieldType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProtoFieldType

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

Formats the value using the given formatter.

impl PartialEq for ProtoFieldType

fn eq(&self, other: &ProtoFieldType) -> 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.
