Struct tor_cell::relaycell::StreamId

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

Identify a single stream on a circuit.

These identifiers are local to each hop on a circuit. This can’t be zero; if you need something that can be zero in the protocol, use Option<StreamId>.

Implementations

impl StreamId

pub fn new(stream_id: u16) -> Option<Self>

Creates a StreamId for non-zero stream_id.

Returns None when stream_id is zero. Messages with a zero/None stream ID apply to the circuit as a whole instead of a particular stream.

pub fn get_or_zero(stream_id: Option<Self>) -> u16

Convenience function to convert to a u16; None is mapped to 0.

Trait Implementations

impl Clone for StreamId

fn clone(&self) -> StreamId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StreamId

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

Formats the value using the given formatter.

impl Display for StreamId

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

Formats the value using the given formatter.

impl From<NonZeroU16> for StreamId

fn from(id: NonZeroU16) -> Self

Converts to this type from the input type.

impl From<StreamId> for NonZeroU16

fn from(id: StreamId) -> NonZeroU16

Converts to this type from the input type.

impl From<StreamId> for u16

fn from(id: StreamId) -> u16

Converts to this type from the input type.

impl Hash for StreamId

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 StreamId

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

This method tests for self and other values to be equal, and is used by ==.

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

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