PreconditionsV2 is an XDR Struct defines as:

struct PreconditionsV2
{
    TimeBounds* timeBounds;

    // Transaction only valid for ledger numbers n such that
    // minLedger <= n < maxLedger (if maxLedger == 0, then
    // only minLedger is checked)
    LedgerBounds* ledgerBounds;

    // If NULL, only valid when sourceAccount's sequence number
    // is seqNum - 1.  Otherwise, valid when sourceAccount's
    // sequence number n satisfies minSeqNum <= n < tx.seqNum.
    // Note that after execution the account's sequence number
    // is always raised to tx.seqNum, and a transaction is not
    // valid if tx.seqNum is too high to ensure replay protection.
    SequenceNumber* minSeqNum;

    // For the transaction to be valid, the current ledger time must
    // be at least minSeqAge greater than sourceAccount's seqTime.
    Duration minSeqAge;

    // For the transaction to be valid, the current ledger number
    // must be at least minSeqLedgerGap greater than sourceAccount's
    // seqLedger.
    uint32 minSeqLedgerGap;

    // For the transaction to be valid, there must be a signature
    // corresponding to every Signer in this array, even if the
    // signature is not otherwise required by the sourceAccount or
    // operations.
    SignerKey extraSigners<2>;

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn clone(&self) -> PreconditionsV2

Returns a copy of the value.

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

Performs copy-assignment from source.

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for PreconditionsV2

fn cmp(&self, other: &PreconditionsV2) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

fn eq(&self, other: &PreconditionsV2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
