getI256Encoder

function getI256Encoder(config?): FixedSizeEncoder<number | bigint, 32>;

Returns an encoder for 256-bit signed integers (i256).

This encoder serializes i256 values using 32 bytes. Values can be provided as either number or bigint.

For more details, see getI256Codec.

`config`	`NumberCodecConfig`	Optional configuration to specify endianness (little by default).

FixedSizeEncoder<number | bigint, 32>

A FixedSizeEncoder<number | bigint, 32> for encoding i256 values.

Encoding an i256 value.

const encoder = getI256Encoder();
const bytes = encoder.encode(-42n); // 0xd6ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
