Available on crate feature parquet_encryption only.

Trait for types that generate file encryption and decryption properties to write and read encrypted Parquet files. This allows flexibility in how encryption keys are managed, for example, to integrate with a user’s key management service (KMS). For example usage, see the parquet_encrypted_with_kms example.

Required Methods

fn get_file_encryption_properties<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, config: &'life1 EncryptionFactoryOptions, schema: &'life2 SchemaRef, file_path: &'life3 Path, ) -> Pin<Box<dyn Future<Output = Result<Option<FileEncryptionProperties>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Generate file encryption properties to use when writing a Parquet file.

fn get_file_decryption_properties<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, config: &'life1 EncryptionFactoryOptions, file_path: &'life2 Path, ) -> Pin<Box<dyn Future<Output = Result<Option<FileDecryptionProperties>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Generate file decryption properties to use when reading a Parquet file.
