Expand description

Represents a field in a record Avro schema.

Fields§

§name: String

Name of the field.

§doc: Documentation

Documentation of the field.

§aliases: Option<Vec<String>>

Aliases of the field’s name. They have no namespace.

§default: Option<Value>

Default value of the field. This value will be used when reading Avro datum if schema resolution is enabled.

§schema: Schema

Schema of the field.

§order: RecordFieldOrder

Order of the field.

NOTE This currently has no effect.

§position: usize

Position of the field in the list of field of its parent Schema

§custom_attributes: BTreeMap<String, Value>

A collection of all unknown fields in the record field.

Implementations§

source§

impl RecordField

source

pub fn is_nullable(&self) -> bool

Returns true if this RecordField is nullable, meaning the schema is a UnionSchema where the first variant is Null.

Trait Implementations§

source§

impl Clone for RecordField

source§

fn clone(&self) -> RecordField

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl Debug for RecordField

source§

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

source§

impl PartialEq for RecordField

source§

fn eq(&self, other: &RecordField) -> bool

Tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
