Crate hyperstack_macros 

hyperstack-macros

Procedural macros for defining HyperStack streams.

This crate provides the #[hyperstack] attribute macro that transforms annotated Rust structs into full streaming pipeline specifications, including:

• State struct generation with field accessors
• Handler creation functions for event processing
• IDL/Proto parser integration for Solana programs
• Automatic AST serialization for deployment

Module Usage (IDL-based)

use hyperstack_macros::{hyperstack, Stream};

#[hyperstack(idl = "idl.json")]
pub mod my_stream {
    #[entity(name = "MyEntity")]
    #[derive(Stream)]
    struct Entity {
        #[map(from = "MyAccount", field = "value")]
        pub value: u64,
    }
}

Supported Attributes

• #[map(...)] - Map from account fields
• #[from_instruction(...)] - Map from instruction fields
• #[event(...)] - Capture instruction events
• #[snapshot(...)] - Capture entire source data
• #[aggregate(...)] - Aggregate field values
• #[computed(...)] - Computed fields from other fields
• #[derive_from(...)] - Derive values from instructions
