Struct PriorityTree 

pub struct PriorityTree {
    pub priorities: Vec<(u32, u32, u8, bool)>,
}

PRIORITY frame pattern for browser fingerprinting.

Different browsers send PRIORITY frames with different dependency trees. Format: (stream_id, depends_on_stream_id, weight, exclusive)

• exclusive: true means this stream replaces all dependencies of the parent
• weight: 1-256, higher means more bandwidth allocation

Fields

priorities: Vec<(u32, u32, u8, bool)>

Priority frames to send: (stream_id, depends_on, weight, exclusive)

Implementations

impl PriorityTree

pub fn chrome() -> Self

Chrome PRIORITY frame pattern.

Chrome sends PRIORITY frames for streams 3,5,7,9,11:

• Stream 3: depends on 0 (root), weight 201
• Stream 5: depends on 0 (root), weight 101
• Stream 7: depends on 0 (root), weight 1
• Stream 9: depends on 7, weight 1
• Stream 11: depends on 3, weight 1

Akamai format: 3:0:0:201,5:0:0:101,7:0:0:1,9:0:7:1,11:0:3:1

pub fn firefox() -> Self

Firefox PRIORITY frame pattern.

Firefox sends PRIORITY frames for streams that haven’t been opened yet, establishing a dependency tree for future streams. Firefox uses a different pattern than Chrome.

The exact Firefox HTTP/2 fingerprint pattern requires verification against real browser traffic captures. This is a placeholder based on Firefox’s known behavior of sending PRIORITY frames for unopened streams.

pub fn none() -> Self

No PRIORITY frames (some clients don’t send them).

Trait Implementations

impl Clone for PriorityTree

fn clone(&self) -> PriorityTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PriorityTree

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

Formats the value using the given formatter.

impl PartialEq for PriorityTree

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