# txline
Devnet-only Rust SDK for TxLINE.
> This crate intentionally supports TxLINE Devnet only. Mainnet constants,
> feature flags, examples, and transaction flows are out of scope for this SDK
> version.
## Overview
`txline` provides typed Rust helpers for the current TxLINE Devnet APIs and
Solana program addresses:
- Devnet configuration and client construction.
- Guest JWT and activated API token handling.
- REST clients for fixtures, odds, scores, validation, and purchase quotes.
- SSE odds and scores streams with reconnect support and heartbeat filtering.
- Legacy and V2 score stat-validation DTOs.
- Devnet PDA and `subscribe(service_level_id, weeks)` transaction helpers.
## Quick Start
```rust,no_run
use txline::{ApiToken, GuestJwt, TxlineClient, TxlineConfig};
# async fn run() -> txline::Result<()> {
let client = TxlineClient::new(TxlineConfig::devnet())?;
let guest = client.start_guest_session().await?;
let message = client.activation_preimage("SUBSCRIBE_TX_SIGNATURE", &[])?;
client.set_guest_jwt(GuestJwt::new(guest.token.as_str())?);
client.set_api_token(ApiToken::new("activated-api-token")?);
let fixtures = client.fixtures().snapshot(None, None).await?;
println!("fixtures: {}", fixtures.len());
# Ok(())
# }
```
The activation preimage is:
```text
${txSig}:${selectedLeagues.join(",")}:${jwt}
```
For the standard bundle with no selected leagues:
```text
${txSig}::${jwt}
```
