Struct soroban_sdk::ledger::Ledger

source ·
pub struct Ledger(/* private fields */);
Expand description

Ledger retrieves information about the current ledger.

§Examples

use soroban_sdk::Env;

let ledger = env.ledger();

let protocol_version = ledger.protocol_version();
let sequence = ledger.sequence();
let timestamp = ledger.timestamp();
let network_id = ledger.network_id();

Implementations§

source§

impl Ledger

source

pub fn protocol_version(&self) -> u32

Returns the version of the protocol that the ledger created with.

source

pub fn sequence(&self) -> u32

Returns the sequence number of the ledger.

The sequence number is a unique number for each ledger that is sequential, incremented by one for each new ledger.

source

pub fn timestamp(&self) -> u64

Returns a unix timestamp for when the ledger was closed.

The timestamp is the number of seconds, excluding leap seconds, that have elapsed since unix epoch. Unix epoch is January 1st, 1970, at 00:00:00 UTC.

source

pub fn network_id(&self) -> BytesN<32>

Returns the network identifier.

This is SHA-256 hash of the network passphrase, for example for the Public Network this returns:

SHA256(Public Global Stellar Network ; September 2015)

Returns for the Test Network:

SHA256(Test SDF Network ; September 2015)
