reverseDecoder

reverseDecoder<TTo, TSize>(decoder): FixedSizeDecoder<TTo, TSize>

Reverses the bytes of a fixed-size decoder.

Given a FixedSizeDecoder, this function returns a new FixedSizeDecoder that reverses the bytes within the fixed-size byte array before decoding.

This can be useful to modify endianness or for other byte-order transformations.

For more details, see reverseCodec.

Type Parameters

Parameters

Returns

FixedSizeDecoder<TTo, TSize>

A new decoder that reads bytes in reverse order.

Example

Decoding a reversed u16 value.

const decoder = reverseDecoder(getU16Decoder({ endian: Endian.Big }));
const value = decoder.decode(new Uint8Array([0x34, 0x12])); // 0x1234 (bytes are flipped back)
