const getI64Encoder: (config?) => FixedSizeEncoder<bigint | number, 8>

Returns an encoder for 64-bit signed integers (i64).

This encoder serializes i64 values using 8 bytes. Values can be provided as either number or bigint.

Parameter	Type	Description
`config?`	`NumberCodecConfig`	Optional configuration to specify endianness (little by default).

FixedSizeEncoder<bigint | number, 8>

A FixedSizeEncoder<number | bigint, 8> for encoding i64 values.

Encoding an i64 value.

const encoder = getI64Encoder();
const bytes = encoder.encode(-42n); // 0xd6ffffffffffffff
