Tag Definitions

Variants

DownloadPiece = 0

Download the content of a piece from a peer. It is composed of {Task ID}{Piece ID}, where the Task ID is a SHA-256 value and the Piece ID is a number.

PieceContent = 1

The content of a piece, with a maximum size of 4 GiB per piece.

DownloadPersistentPiece = 2

Download the content of a persistent piece from a peer. It is composed of {Task ID}{Piece ID}, where the Task ID is a SHA-256 value and the Piece ID is a number.

PersistentPieceContent = 3

The content of a persistent piece, with a maximum size of 4 GiB per piece.

DownloadPersistentCachePiece = 4

Download the content of a persistent cache piece from a peer. It is composed of {Task ID}{Piece ID}, where the Task ID is a SHA-256 value and the Piece ID is a number.

PersistentCachePieceContent = 5

The content of a persistent cache piece, with a maximum size of 4 GiB per piece.

DownloadCachePiece = 6

Download the content of a cache piece from a peer. It is composed of {Task ID}{Piece ID}, where the Task ID is a SHA-256 value and the Piece ID is a number.

CachePieceContent = 7

The content of a cache piece, with a maximum size of 4 GiB per piece.

Reserved(u8)

Reserved for future use, for tags 6-254.

Close = 254

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Tag

impl From<Tag> for u8

Implement From for u8.

fn from(tag: Tag) -> Self

impl PartialEq for Tag

fn eq(&self, other: &Tag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
