Represents an Avro value

Variants

Null

A null value.

Int(i32)

An i32 integer value.

Long(i64)

An i64 long value.

Boolean(bool)

A boolean value.

Float(f32)

A f32 float value.

Double(f64)

A f64 float value.

Record(Record)

A Record value (BTreeMap<String, Value>).

Fixed(Vec<u8>)

A Fixed value.

Map(HashMap<String, Value>)

A Map value.

Bytes(Vec<u8>)

A sequence of u8 bytes.

Str(String)

Rust strings map directly to avro strings

Union(Box<Value>)

A union is a sequence of unique Values

Enum(String)

An enumeration. Unlike Rust enums, enums in avro don't support data within their variants.

Array(Vec<Value>)

An array of Values

Byte(u8)

auxiliary u8 helper for serde. Not an avro value.
