Event Emission Example — Anchor Code
Emits an event when a function is called in an Anchor program.
#[program]
mod events {
use super::*;
pub fn trigger_event(ctx: Context<Trigger>, value: u64) -> Result<()> {
emit!(MyEvent { value });
Ok(())
}
#[event]
pub struct MyEvent {
pub value: u64,
}
#[derive(Accounts)]
pub struct Trigger<'info> {}
}Anchor Language Guide
Anchor is a Rust-based framework for Solana smart contract (program) development, testing, and deployment. It simplifies building Solana dApps by providing a high-level abstraction over Solana programs and client interactions.
Primary Use Cases
- ▸Writing Solana smart contracts in Rust
- ▸Generating client interfaces (IDL) for programs
- ▸Testing programs with simulated Solana clusters
- ▸Deploying Solana programs to devnet/testnet/mainnet
- ▸Automating transactions and client-side interactions
Notable Features
- ▸Rust-based Solana program development
- ▸IDL generation for client libraries
- ▸Anchor CLI for scaffolding, building, and deploying programs
- ▸Testing framework integrated with Solana local validator
- ▸Macros to reduce boilerplate for accounts, instructions, and errors
Origin & Creator
Anchor was created by Project Serum team members in 2020 to simplify Solana program development, reduce boilerplate, and improve developer productivity.
Industrial Note
Anchor is widely used in DeFi, NFT, and other Solana ecosystem projects, as it standardizes Solana program structure and automates common patterns like account validation and serialization.
