Struct StreamId

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

A stream identifier, as described in Section 5.1.1 of RFC 7540.

Streams are identified with an unsigned 31-bit integer. Streams initiated by a client MUST use odd-numbered stream identifiers; those initiated by the server MUST use even-numbered stream identifiers. A stream identifier of zero (0x0) is used for connection control messages; the stream identifier of zero cannot be used to establish a new stream.

Implementations

impl StreamId

pub const ZERO: StreamId

Stream ID 0.

pub const MAX: StreamId

The maximum allowed stream ID.

pub fn parse(buf: &[u8]) -> (StreamId, bool)

Parse the stream ID

pub fn is_client_initiated(&self) -> bool

Returns true if this stream ID corresponds to a stream that was initiated by the client.

pub fn is_server_initiated(&self) -> bool

Returns true if this stream ID corresponds to a stream that was initiated by the server.

pub fn zero() -> StreamId

Return a new StreamId for stream 0.

pub fn is_zero(&self) -> bool

Returns true if this stream ID is zero.

pub fn next_id(&self) -> Result<StreamId, StreamIdOverflow>

Returns the next stream ID initiated by the same peer as this stream ID, or an error if incrementing this stream ID would overflow the maximum.

Trait Implementations

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StreamId

fn deserialize<D>( deserializer: D, ) -> Result<StreamId, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

where __H: Hasher,

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 Ord for StreamId

fn cmp(&self, other: &StreamId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl PartialEq<u32> for StreamId

fn eq(&self, other: &u32) -> bool

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

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