Implementations

impl Schema

pub fn top_node(&self) -> SchemaNode<'_>

pub fn top_node_or_named(&self) -> SchemaNodeOrNamed<'_>

pub fn lookup(&self, idx: usize) -> &NamedSchemaPiece

pub fn try_lookup_name(&self, name: &FullName) -> Option<&NamedSchemaPiece>

impl Schema

pub fn parse(value: &Value) -> Result<Schema, Error>

Create a Schema from a serde_json::Value representing a JSON Avro schema.

pub fn canonical_form(&self) -> String

Converts self into its Parsing Canonical Form.

pub fn fingerprint<D>(&self) -> SchemaFingerprintwhere
    D: Digest,

Generate fingerprint of Schema’s Parsing Canonical Form.

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl<'a> From<&'a Schema> for SchemaKind

fn from(schema: &'a Schema) -> SchemaKind

Converts to this type from the input type.

impl FromStr for Schema

fn from_str(input: &str) -> Result<Schema, Error>

Create a Schema from a string representing a JSON Avro schema.

type Err = Error

The associated error which can be returned from parsing.

impl PartialEq<Schema> for Schema

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Schema

fn serialize<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.

impl ToString for Schema

fn to_string(&self) -> String

Converts the given value to a String.
