LedgerHeader is an XDR Struct defines as:

struct LedgerHeader
{
    uint32 ledgerVersion;    // the protocol version of the ledger
    Hash previousLedgerHash; // hash of the previous ledger header
    StellarValue scpValue;   // what consensus agreed to
    Hash txSetResultHash;    // the TransactionResultSet that led to this ledger
    Hash bucketListHash;     // hash of the ledger state

    uint32 ledgerSeq; // sequence number of this ledger

    int64 totalCoins; // total number of stroops in existence.
                      // 10,000,000 stroops in 1 XLM

    int64 feePool;       // fees burned since last inflation run
    uint32 inflationSeq; // inflation sequence number

    uint64 idPool; // last used global ID, used for generating objects

    uint32 baseFee;     // base fee per operation in stroops
    uint32 baseReserve; // account base reserve in stroops

    uint32 maxTxSetSize; // maximum size a transaction set can be

    Hash skipList[4]; // hashes of ledgers in the past. allows you to jump back
                      // in time without walking the chain back ledger by ledger
                      // each slot contains the oldest ledger that is mod of
                      // either 50  5000  50000 or 500000 depending on index
                      // skipList[0] mod(50), skipList[1] mod(5000), etc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LedgerHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LedgerHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for LedgerHeader

fn cmp(&self, other: &LedgerHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,
