Variants

Null

A null Avro value.

Boolean(bool)

A boolean Avro value.

Int(i32)

A int Avro value.

Long(i64)

A long Avro value.

Float(f32)

A float Avro value.

Double(f64)

A double Avro value.

Bytes(Vec<u8>)

A bytes Avro value.

String(String)

A string Avro value.

Fixed(usize, Vec<u8>)

A fixed Avro value. The size of the fixed value is represented as a usize.

Enum(i32, String)

An enum Avro value.

An Enum is represented by a symbol and its position in the symbols list of its corresponding schema. This allows schema-less encoding, as well as schema resolution while reading values.

Union(Box<Value>)

An union Avro value.

Array(Vec<Value>)

An array Avro value.

Map(HashMap<String, Value, RandomState>)

A map Avro value.

Record(Vec<(String, Value)>)

A record Avro value.

A Record is represented by a vector of (<record name>, value). This allows schema-less encoding.

See Record for a more user-friendly support.

Methods

impl Value

pub fn validate(&self, schema: &Schema) -> bool

Validate the value against the given Schema.

See the Avro specification for the full set of rules of schema validation.

pub fn resolve(self, schema: &Schema) -> Result<Value, Error>

Attempt to perform schema resolution on the value, with the given Schema.

See Schema Resolution in the Avro specification for the full set of rules of schema resolution.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq<Value> for Value

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

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

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

This method tests for !=.

impl StructuralPartialEq for Value

impl ToAvro for Value

fn avro(self) -> Value

Transforms this value into an Avro-compatible Value.
