Crate tds_protocol 

tds-protocol

Pure implementation of the MS-TDS (Tabular Data Stream) protocol used by Microsoft SQL Server.

This crate provides no_std compatible packet structures, token parsing, and serialization for TDS protocol versions 7.4 through 8.0.

Features

• std (default): Enable standard library support
• alloc: Enable allocation without full std (requires alloc crate)

Design Philosophy

This crate is intentionally IO-agnostic. It contains no networking logic and makes no assumptions about the async runtime. Higher-level crates build upon this foundation to provide async I/O capabilities.

Example

use tds_protocol::{PacketHeader, PacketType, PacketStatus};

let header = PacketHeader {
    packet_type: PacketType::SqlBatch,
    status: PacketStatus::END_OF_MESSAGE,
    length: 100,
    spid: 0,
    packet_id: 1,
    window: 0,
};
