Struct ServerStatSnapshot 

pub struct ServerStatSnapshot {
    pub host: String,
    pub download_speed: u64,
    pub single_connection_avg_speed: u64,
    pub multi_connection_avg_speed: u64,
    pub last_updated: u64,
    pub status: u32,
    pub counter: u32,
    pub last_error_time: Option<u64>,
    pub last_error_code: u16,
    pub consecutive_failures: u32,
}

Serializable snapshot of ServerStat for persistence.

This struct contains all the persistent fields of ServerStat in a serde-compatible format (no atomic types). Used for saving and loading server performance statistics across restarts.

Example

use aria2_core::selector::server_stat::{ServerStat, ServerStatSnapshot};

let stat = ServerStat::new("mirror.example.com");
stat.update_speed(5000, false);

let snapshot = stat.to_snapshot();
let restored = ServerStat::from_snapshot(&snapshot);

assert_eq!(restored.host, stat.host);

Fields

host: String

Server hostname (e.g., “mirror1.example.com”)

download_speed: u64

Current download speed in bytes/sec

single_connection_avg_speed: u64

Exponential moving average of single-connection download speed

multi_connection_avg_speed: u64

Exponential moving average of multi-connection download speed

last_updated: u64

Unix timestamp of last update

status: u32

Server status: 0 = OK, 1 = Error

counter: u32

Usage counter (number of times this server was selected)

last_error_time: Option<u64>

Unix timestamp of last error (None if never failed)

last_error_code: u16

HTTP error code of last error (0 if never failed)

consecutive_failures: u32

Number of consecutive failures (reset on success)
