Struct Deserializer 

#[non_exhaustive]
pub struct Deserializer {
    pub open_x_json_ser_de: Option<OpenXJsonSerDe>,
    pub hive_json_ser_de: Option<HiveJsonSerDe>,
}

The deserializer you want Firehose to use for converting the input data from JSON. Firehose then serializes the data to its final format using the Serializer. Firehose supports two types of deserializers: the Apache Hive JSON SerDe and the OpenX JSON SerDe.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

open_x_json_ser_de: Option<OpenXJsonSerDe>

The OpenX SerDe. Used by Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the native Hive / HCatalog JsonSerDe.

hive_json_ser_de: Option<HiveJsonSerDe>

The native Hive / HCatalog JsonSerDe. Used by Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the OpenX SerDe.

Implementations

impl Deserializer

pub fn open_x_json_ser_de(&self) -> Option<&OpenXJsonSerDe>

The OpenX SerDe. Used by Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the native Hive / HCatalog JsonSerDe.

pub fn hive_json_ser_de(&self) -> Option<&HiveJsonSerDe>

The native Hive / HCatalog JsonSerDe. Used by Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the OpenX SerDe.

impl Deserializer

pub fn builder() -> DeserializerBuilder

Creates a new builder-style object to manufacture Deserializer.

Trait Implementations

impl Clone for Deserializer

fn clone(&self) -> Deserializer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Deserializer

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

Formats the value using the given formatter.

impl PartialEq for Deserializer

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