getI64Decoder

const getI64Decoder: (config?) => FixedSizeDecoder<bigint, 8>;

Returns a decoder for 64-bit signed integers (i64).

This decoder deserializes i64 values from 8 bytes. The decoded value is always a bigint.

For more details, see getI64Codec.

Parameters

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

A FixedSizeDecoder<bigint, 8> for decoding i64 values.

Decoding an i64 value.

const decoder = getI64Decoder();
const value = decoder.decode(new Uint8Array([
  0xd6, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff
])); // -42n
