Crate soroban_sdk

Expand description

Soroban SDK supports writing programs for the Soroban smart contract platform.

Docs

See soroban.stellar.org for documentation.

Examples

use soroban_sdk::{contractimpl, symbol, vec, BytesN, Env, Symbol, Vec};

pub struct HelloContract;

#[contractimpl]
impl HelloContract {
    pub fn hello(env: Env, to: Symbol) -> Vec<Symbol> {
        vec![&env, symbol!("Hello"), to]
    }
}

#[test]
fn test() {
    let env = Env::default();
    let contract_id = env.register_contract(None, HelloContract);
    let client = HelloContractClient::new(&env, &contract_id);

    let words = client.hello(&symbol!("Dev"));

    assert_eq!(words, vec![&env, symbol!("Hello"), symbol!("Dev"),]);
}

Macros

assert_with_error

Assert a condition and panic with the given error if it is false.

Create a Bytes with an array, or an integer or hex literal.

Create a BytesN with an array, or an integer or hex literal.

Import a contract from its WASM file, generating a constant holding the contract file.

Import a contract from its WASM file, generating a client, types, and constant holding the contract file.

Log a debug event.

Create a Map with the given key-value pairs.

panic_with_error

Panic with the given error.

Create a Symbol with the given string.

Create a Vec with the given items.

Structs

Address is a universal opaque identifier to use in contracts.

Bytes is a contiguous growable array type containing u8s.

BytesN is a contiguous fixed-size array type containing u8s.

ConversionError

Error type indicating a failure to convert some type to another; details of the failed conversion will typically be written to the debug log.

The Env type provides access to the environment the contract is executing within.

Map is a ordered key-value dictionary.

Raw value of the Soroban smart contract platform that types can be converted to and from for storing, or passing between contracts.

Symbol reprents strings up to 10 characters long with a a-zA-Z0-9_ alphabet encoded into a 60-bit space between 10 characters long.

Vec is a sequential and indexable growable collection type.
