Represents any valid Avro value More information about Avro values can be found in the Avro Specification

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.

Date(i32)

A Date coming from an avro Logical Date, which is an i32 number of days since the Unix epoch.

Timestamp(NaiveDateTime)

A DateTime coming from an avro Logical Timestamp

Decimal(DecimalValue)

A decimal Avro value

The value of the decimal can be computed as follows: unscaled × 10-scale.

Bytes(Vec<u8>)

A bytes Avro value.

String(String)

A string Avro value.

Fixed(usizeVec<u8>)

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

Enum(usizeString)

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

Fields

index: usize

The index of this variant in the reader schema

inner: Box<Value>

The value of the variant

n_variants: usize

The number of variants in the reader schema

null_variant: Option<usize>

Which variant is null in the reader schema.

An union Avro value.

Array(Vec<Value>)

An array Avro value.

Map(AvroMap)

A map Avro value.

Record(Vec<(String, Value)>)

A record Avro value.

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

See Record for a more user-friendly support.

Json(Value)

A string Avro value that has been interpreted as JSON.

This is not part of the Avro spec, but is emitted by Debezium, and distinguished by setting the "connect.name" property to "io.debezium.data.Json".

Uuid(Uuid)

A Uuid coming from an avro Logical uuid.

Implementations

Validate the value against the given Schema.

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

Trait Implementations

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Returns the “default value” for a type. Read more
