⚠️ DEPRECATED: ntp_usg

This crate is deprecated as of version 3.0.0 and is no longer maintained.

The monolithic ntp_usg crate has been split into three focused, well-maintained crates:

Crate	Description	Documentation
`ntp_usg-proto`	NTP protocol types, extension fields, and NTS cryptographic primitives	docs.rs
`ntp_usg-client`	NTP client library with sync, async (tokio/smol), and NTS support	docs.rs
`ntp_usg-server`	NTP server library with tokio/smol and NTS-KE support	docs.rs

Why was this crate split?

The split provides several benefits:

Reduced dependencies: Use only what you need (client, server, or just protocol types)
Faster compile times: Smaller crates compile faster
Better maintainability: Each crate has a focused purpose
Clearer documentation: Each crate's docs focus on its specific use case
Independent versioning: Each component can evolve at its own pace

Migration Guide

For NTP Client Users

Before (v2.x):

[dependencies]
ntp_usg = "2.0"

use ntp_usg::request;

fn main() {
    let response = request("time.nist.gov:123").unwrap();
    println!("Offset: {} seconds", response.offset_seconds);
}

After (v3.x):

[dependencies]
ntp_usg-client = "3.0"

use ntp_client::request;

fn main() {
    let response = request("time.nist.gov:123").unwrap();
    println!("Offset: {} seconds", response.offset_seconds);
}

For NTP Server Users

After (v3.x):

[dependencies]
ntp_usg-server = { version = "3.0", features = ["tokio"] }

use ntp_server::*;
// See ntp_usg-server documentation for examples

For Protocol/Type Users

If you only need NTP protocol types and parsing (no network I/O):

[dependencies]
ntp_usg-proto = "3.0"

use ntp_proto::{protocol::*, unix_time::*};

Feature Flags

The new crates use more granular feature flags:

ntp_usg-proto: std (default), alloc, nts
ntp_usg-client: tokio, nts, clock, smol-runtime, nts-smol
ntp_usg-server: tokio, nts, smol-runtime, nts-smol

See each crate's documentation for detailed feature information.

Compatibility

This v3.0.0 release of ntp_usg re-exports all three new crates for backwards compatibility, but you will receive deprecation warnings. We strongly recommend migrating to the new crates.

Versions 2.0.3 and below have been yanked from crates.io to encourage migration.
