pub struct PlainEncoder<T: DataType> { /* fields omitted */ }
Plain encoding that supports all types.
Values are encoded back to back.
The plain encoding is used whenever a more efficient encoding can not be used.
It stores the data in the following format:
- BOOLEAN - 1 bit per value, 0 is false; 1 is true.
- INT32 - 4 bytes per value, stored as little-endian.
- INT64 - 8 bytes per value, stored as little-endian.
- FLOAT - 4 bytes per value, stored as IEEE little-endian.
- DOUBLE - 8 bytes per value, stored as IEEE little-endian.
- BYTE_ARRAY - 4 byte length stored as little endian, followed by bytes.
- FIXED_LEN_BYTE_ARRAY - just the bytes are stored.
Creates new plain encoder.

Returns the encoding type of this encoder.
Returns an estimate of the encoded data, in bytes. Method call must be O(1). Read more
Flushes the underlying byte buffer that's being processed by this encoder, and return the immutable copy of it. This will also reset the internal state. Read more

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
