Trait ArrayEncoder 

Source 
pub trait ArrayEncoder:
    Debug
    + Send
    + Sync {
    // Required method
    fn encode(
        &self,
        data: DataBlock,
        data_type: &DataType,
        buffer_index: &mut u32,
    ) -> Result<EncodedArray>;
}
Expand description

Encodes data from one format to another (hopefully more compact or useful) format

The array encoder must be Send + Sync. Encoding is always done on its own thread task in the background and there could potentially be multiple encode tasks running for a column at once.

Required Methods§

Source

fn encode( &self, data: DataBlock, data_type: &DataType, buffer_index: &mut u32, ) -> Result<EncodedArray>

Encode data

The result should contain a description of the encoding that was chosen. This can be used to decode the data later.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
