Provides the macros needed to write fvm contracts

Basic Usage

Macros can be used in contract for simplify contract preparation process´╝î like this:

use fvm_macros::contract;
use fvm_macros::storage;
use fvm_std::collections::hyper_map::HyperMap;

#[storage]
pub struct SetHash {
    map: HyperMap<String, String>,
}

#[contract]
impl SetHash {
    fn new() -> Self {
        Self { map: HyperMap::new() }
    }

    pub fn set_hash(&mut self, key: String, value: String) {
        self.map.insert(key, value);
    }

    pub fn get_hash(&mut self, key: String) -> &String {
        self.map.get(&key).unwrap()
    }
}

Contract Mode

Now write contract have two mode:

  • normal mode

Contract with normal mode limited data storage format, and user can write contract more convenient. User can use all macros except advance_contract.

  • advance mode

Contract with advance mode not limited data storage format, and it must open advance feature with fvm-std and 'fvm-macros' lib to use this mode. The execute speed of contract in this mode would be fast then the contract in normal mode.
