Implementations

impl UnionSchema

pub(crate) fn new(schemas: Vec<SchemaPieceOrNamed>) -> Result<Self, AvroError>

pub fn variants(&self) -> &[SchemaPieceOrNamed]

Returns a slice to all variants of this schema.

pub fn is_nullable(&self) -> bool

Returns true if the first variant of this UnionSchema is Null.

pub fn match_piece( &self, sp: &SchemaPiece, ) -> Option<(usize, &SchemaPieceOrNamed)>

pub fn match_ref( &self, other: SchemaPieceRefOrNamed<'_>, names_map: &BTreeMap<usize, usize>, ) -> Option<(usize, &SchemaPieceOrNamed)>

pub fn match_( &self, other: &SchemaPieceOrNamed, names_map: &BTreeMap<usize, usize>, ) -> Option<(usize, &SchemaPieceOrNamed)>

Trait Implementations

impl Clone for UnionSchema

fn clone(&self) -> UnionSchema

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnionSchema

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

Formats the value using the given formatter.

impl PartialEq for UnionSchema

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