Struct AvroField 

pub struct AvroField {
    name: String,
    data_type: AvroDataType,
}

A named AvroDataType

Fields

name: String

data_type: AvroDataType

Implementations

impl AvroField

pub fn field(&self) -> Field

Returns the arrow [Field]

pub fn data_type(&self) -> &AvroDataType

Returns the AvroDataType

pub fn with_utf8view(&self) -> Self

Returns a new AvroField with Utf8View support enabled

This will convert any Utf8 codecs to Utf8View codecs. This method is used to enable potential performance optimizations in string-heavy workloads by using Arrow’s StringViewArray data structure.

Returns a new AvroField with the same structure, but with string types converted to use Utf8View instead of Utf8.

pub fn name(&self) -> &str

Returns the name of this Avro field

This is the field name as defined in the Avro schema. It’s used to identify fields within a record structure.

pub(crate) fn resolve_from_writer_and_reader<'a>( writer_schema: &'a Schema<'a>, reader_schema: &'a Schema<'a>, use_utf8view: bool, strict_mode: bool, ) -> Result<Self, ArrowError>

Performs schema resolution between a writer and reader schema.

This is the primary entry point for handling schema evolution. It produces an AvroField that contains all the necessary information to read data written with the writer schema as if it were written with the reader schema.

Trait Implementations

impl AvroFieldExt for AvroField

fn with_utf8view(&self) -> Self

Returns a new field with Utf8View support enabled for string data

impl Clone for AvroField

fn clone(&self) -> AvroField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AvroField

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

Formats the value using the given formatter.

impl PartialEq for AvroField

fn eq(&self, other: &AvroField) -> 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> TryFrom<&Schema<'a>> for AvroField

type Error = ArrowError

The type returned in the event of a conversion error.

fn try_from(schema: &Schema<'a>) -> Result<Self, Self::Error>

Performs the conversion.
