Struct SessionId 

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

Identifier for a browser session (Firefox window/process).

Generated by an atomic counter starting at 1. Each call to SessionId::next() returns a unique, incrementing ID. Thread-safe and lock-free.

Example

let session1 = SessionId::next();
let session2 = SessionId::next();
assert!(session1.as_u32() < session2.as_u32());

Implementations

impl SessionId

pub fn next() -> Self

Generates the next unique session ID.

Uses an atomic counter that starts at 1 and increments. Thread-safe and lock-free.

Panics

Panics if counter overflows (after 2^32 - 1 sessions).

pub fn from_u32(id: u32) -> Option<Self>

Creates a SessionId from a u32 value.

Used for parsing session IDs from READY messages.

Returns

Some(SessionId) if id > 0, None otherwise.

pub const fn as_u32(&self) -> u32

Returns the underlying u32 value.

Trait Implementations

impl Clone for SessionId

fn clone(&self) -> SessionId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionId

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SessionId

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

Formats the value using the given formatter.

impl Hash for SessionId

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 Ord for SessionId

fn cmp(&self, other: &SessionId) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SessionId

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

impl PartialOrd for SessionId

fn partial_cmp(&self, other: &SessionId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SessionId

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
