Struct H2ConnectionConfig 

pub struct H2ConnectionConfig {
    pub initial_connection_window: u32,
    pub max_concurrent_streams: u32,
    pub stream_shrink_ratio: u32,
}

Configurable H2 connection tuning parameters.

All values have safe defaults. When configured via listener config, absent values fall back to compile-time defaults.

Fields

initial_connection_window: u32

Connection-level receive window size in bytes (RFC 9113 §6.9.2).

max_concurrent_streams: u32

Maximum concurrent streams (SETTINGS_MAX_CONCURRENT_STREAMS).

stream_shrink_ratio: u32

Shrink threshold ratio for recycled stream slots.

Implementations

impl H2ConnectionConfig

pub fn new( initial_connection_window: u32, max_concurrent_streams: u32, stream_shrink_ratio: u32, ) -> Self

Create a validated config, clamping to safe bounds.

• initial_connection_window: clamped to [65535, 2^31-1] per RFC 9113 §6.9
• max_concurrent_streams: minimum 1
• stream_shrink_ratio: minimum 2 (1 would defeat slot recycling)

pub fn from_optional( window: Option<u32>, max_streams: Option<u32>, shrink_ratio: Option<u32>, ) -> Self

Create from optional config values, falling back to compile-time defaults. Combines unwrap-or-default with validation clamping.

Trait Implementations

impl Clone for H2ConnectionConfig

fn clone(&self) -> H2ConnectionConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for H2ConnectionConfig

impl Debug for H2ConnectionConfig

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

Formats the value using the given formatter.

impl Default for H2ConnectionConfig

fn default() -> Self

Returns the “default value” for a type.

impl Eq for H2ConnectionConfig

impl PartialEq for H2ConnectionConfig

fn eq(&self, other: &H2ConnectionConfig) -> 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.
