Struct DataHash 

pub struct DataHash(/* private fields */);

An opaque hash over associated data, such as an audio file.

The protocol makes no assumption about the hash algorithm. On the wire a hash is a byte string prefixed with its length as u8, where a length of zero signals absence; DataHash itself is therefore never empty, and absence is expressed as Option<DataHash>, which encodes None as a single zero byte.

In practice servers use MD5 (16 bytes); enable the md5 feature for a direct conversion from md5::Digest.

Implementations

impl DataHash

pub fn as_bytes(&self) -> &[u8]

Returns the raw hash bytes.

Trait Implementations

impl Clone for DataHash

fn clone(&self) -> DataHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataHash
