Struct RouteFlags 

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

Route flags (bitflags — multiple flags can be set simultaneously)

Implementations

impl RouteFlags

pub const NONE: Self

No special flags

pub const CONTROL: Self

Control packet (pingwave, capability update)

pub const REQUIRES_ACK: Self

Requires acknowledgment

pub const PRIORITY: Self

Priority packet (skip fairness queue)

pub const END_OF_STREAM: Self

Last packet in stream

pub fn from_u8(v: u8) -> Self

Parse flags from u8.

The & 0x0F mask drops the high nibble. Today the defined flags fit in the low nibble (CONTROL, REQUIRES_ACK, PRIORITY, END_OF_STREAM), so 16 distinct wire bytes alias to the same RouteFlags. The high nibble is reserved: any future flag added there will be silently stripped by old peers running this codepath. When a new flag is introduced:

1. Allocate it in the low nibble if any bit is still free, OR
2. Widen this mask in the same release that defines the new flag, in lock-step across every peer that decodes routing headers (Rust + cross-language bindings). A skew where one peer reads the bit and another masks it off silently diverges on routing semantics.

pub fn as_u8(self) -> u8

Convert to u8

pub fn contains(self, other: Self) -> bool

Check if a flag is set

pub fn is_control(self) -> bool

Check if this is a control packet

pub fn is_priority(self) -> bool

Check if this is a priority packet

Trait Implementations

impl Clone for RouteFlags

fn clone(&self) -> RouteFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RouteFlags

impl Debug for RouteFlags

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

Formats the value using the given formatter.

impl Default for RouteFlags

fn default() -> RouteFlags

Returns the “default value” for a type.

impl Eq for RouteFlags

impl PartialEq for RouteFlags

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