NullableCodecConfig

type NullableCodecConfig<TPrefix> = object;

Defines the configuration options for nullable codecs.

This configuration controls how nullable values are encoded and decoded.

By default, nullable values are prefixed with a u8 (0 = null, 1 = present). The noneValue and prefix options allow customizing this behavior.

Type Parameter	Description
`TPrefix` extends \| `NumberCodec` \| `NumberDecoder` \| `NumberEncoder`	A number codec, encoder, or decoder used as the presence prefix.

optional noneValue: ReadonlyUint8Array | "zeroes";

Specifies how null values are represented in the encoded data.

By default, null values are omitted from encoding.
'zeroes': The bytes allocated for the value are filled with zeroes. This requires a fixed-size codec.
Custom byte array: null values are replaced with a predefined byte sequence. This results in a variable-size codec.

No explicit noneValue is used; null values are omitted.

optional prefix: TPrefix | null;

The presence prefix used to distinguish between null and present values.

By default, a u8 prefix is used (0 = null, 1 = present).
Custom number codec: Allows defining a different number size for the prefix.
null: No prefix is used; noneValue (if provided) determines null. If no noneValue is set, null is identified by the absence of bytes.

u8 prefix.
