# D2-Stampede
Dota 2 replay parser written in Rust.
### Quick Start
```rust
use d2_stampede::prelude::*;
use d2_stampede::proto::*;
// Create struct that implements Default trait
#[derive(Default)]
struct Chat;
// Mark impl block with observer attribute
#[observer]
impl Chat {
#[on_message] // Use on_message attribute to mark protobuf message handler
fn handle_chat_msg(
&mut self,
ctx: &Context,
chat_msg: CDotaUserMsgChatMessage, // Use any protobuf message as an argument
) -> ObserverResult {
if let Ok(pr) = ctx.entities().get_by_class_name("CDOTA_PlayerResource") {
let name: String = property!(
pr,
"m_vecPlayerData.{:04}.m_iszPlayerName",
chat_msg.source_player_id()
);
println!("{}: {}", name, chat_msg.message_text());
}
Ok(())
}
}
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Read replay file
let replay = unsafe { memmap2::Mmap::map(&std::fs::File::open("replay.dem")?)? };
// Create parser
let mut parser = Parser::new(&replay)?;
// Register observers
parser.register_observer::<Chat>();
// Parse replay from start to end
parser.run_to_end()?;
// Or parse only parts of replay
parser.jump_to_tick(10000)?;
parser.run_to_tick(11000)?;
Ok(())
}
```
