Struct MetadataMessage 

pub struct MetadataMessage {
    pub msg_type: MetadataMessageType,
    pub piece: u32,
    pub total_size: Option<u64>,
    pub data: Option<Bytes>,
}

ut_metadata message (BEP 9).

Fields

msg_type: MetadataMessageType

Message type (request, data, or reject).

piece: u32

Zero-based metadata piece index.

total_size: Option<u64>

Total metadata size (included in Data messages).

data: Option<Bytes>

Metadata piece data (appended after the bencode dict for Data messages).

Implementations

impl MetadataMessage

pub fn request(piece: u32) -> Self

Create a request for metadata piece.

pub fn data(piece: u32, total_size: u64, data: Bytes) -> Self

Create a data response for a metadata piece.

pub fn reject(piece: u32) -> Self

Create a reject for metadata piece.

pub fn to_bytes(&self) -> Result<Bytes>

Encode to bytes (bencode dict + optional trailing data).

Errors

Returns an error if serialization fails.

pub fn from_bytes(data: &[u8]) -> Result<Self>

Parse from bytes. The bencode dict may be followed by raw data.

Errors

Returns an error if the data is not a valid metadata message.

Trait Implementations

impl Clone for MetadataMessage

fn clone(&self) -> MetadataMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataMessage

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

Formats the value using the given formatter.

impl PartialEq for MetadataMessage

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