Struct Http2Settings 

pub struct Http2Settings {
    pub initial_stream_window_size: u32,
    pub initial_connection_window_size: u32,
    pub max_frame_size: u32,
    pub adaptive_window: bool,
}

Available on crate feature api only.

HTTP/2 protocol tuning parameters for performance optimization.

Controls flow control windows, frame sizes, and adaptive algorithms to optimize HTTP/2 performance for different use cases from low-latency real-time applications to high-throughput batch processing.

Default Configuration:

• Stream window: 64KB (good for most use cases)
• Connection window: 1MB (allows multiple concurrent streams)
• Frame size: 16KB (HTTP/2 default)
• Adaptive window: Enabled (automatically tunes flow control)

Performance Profiles

• Low latency: Small windows, disabled adaptive algorithms
• High throughput: Large windows, enabled adaptive algorithms
• Real-time: Minimal buffering, predictable flow control
• Batch processing: Maximum windows for bulk transfers

Fields

initial_stream_window_size: u32

initial_connection_window_size: u32

max_frame_size: u32

adaptive_window: bool

Implementations

impl Http2Settings

pub fn new( initial_stream_window_size: u32, initial_connection_window_size: u32, max_frame_size: u32, adaptive_window: bool, ) -> Self

Create custom HTTP/2 tuning parameters.

Parameters

• initial_stream_window_size: Per-stream buffer size (bytes)
• initial_connection_window_size: Total connection buffer size (bytes)
• max_frame_size: Maximum frame size (bytes, 16KB to 16MB)
• adaptive_window: Enable automatic window size adjustment
