Enum ResponseCompressionCodec 

#[non_exhaustive]
pub enum ResponseCompressionCodec {
    Unspecified,
    Lz4,
    UnknownValue(UnknownValue),
}

Specifies which compression codec to attempt on the entire serialized response payload (either Arrow record batch or Avro rows). This is not to be confused with the Apache Arrow native compression codecs specified in ArrowSerializationOptions. For performance reasons, when creating a read session requesting Arrow responses, setting both native Arrow compression and application-level response compression will not be allowed - choose, at most, one kind of compression.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unspecified

Default is no compression.

Lz4

Use raw LZ4 compression.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using ResponseCompressionCodec::value or ResponseCompressionCodec::name.

Implementations

impl ResponseCompressionCodec

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.
