Struct InfoHashes 

pub struct InfoHashes {
    pub v1: Option<Id20>,
    pub v2: Option<Id32>,
}

Holds optional v1 (SHA-1) and v2 (SHA-256) info hashes.

At least one hash must be present. Used throughout the stack as the canonical way to identify a torrent regardless of protocol version.

Fields

v1: Option<Id20>

v1 info hash (SHA-1 of the v1 info dict).

v2: Option<Id32>

v2 info hash (SHA-256 of the v2 info dict).

Implementations

impl InfoHashes

pub fn v1_only(hash: Id20) -> Self

Create with only a v1 (SHA-1) hash.

pub fn v2_only(hash: Id32) -> Self

Create with only a v2 (SHA-256) hash.

pub fn hybrid(v1: Id20, v2: Id32) -> Self

Create with both v1 and v2 hashes (hybrid torrent).

pub fn has_v1(&self) -> bool

Whether a v1 hash is present.

pub fn has_v2(&self) -> bool

Whether a v2 hash is present.

pub fn is_hybrid(&self) -> bool

Whether both v1 and v2 hashes are present (hybrid torrent).

pub fn best_v1(&self) -> Id20

Get the best available v1 hash for tracker/DHT compatibility.

Returns the v1 hash if present, otherwise truncates the v2 SHA-256 hash to 20 bytes (as specified by BEP 52 for DHT/tracker fallback).

Trait Implementations

impl Clone for InfoHashes

fn clone(&self) -> InfoHashes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InfoHashes

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

Formats the value using the given formatter.

impl Display for InfoHashes

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

Formats the value using the given formatter.

impl Hash for InfoHashes

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InfoHashes

fn eq(&self, other: &InfoHashes) -> 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.

impl Serialize for InfoHashes

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
