Struct LedgerHashes

pub struct LedgerHashes<'a> {
    pub common_fields: CommonFields<'a, NoFlags>,
    pub first_ledger_sequence: u32,
    pub hashes: Vec<Cow<'a, str>>,
    pub last_ledger_sequence: u32,
}

The LedgerHashes object type contains a history of prior ledgers that led up to this ledger version, in the form of their hashes. Objects of this ledger type are modified automatically when closing a ledger. The LedgerHashes objects exist to make it possible to look up a previous ledger’s hash with only the current ledger version and at most one lookup of a previous ledger version.

There are two kinds of LedgerHashes object. Both types have the same fields. Each ledger version contains:

• Exactly one “recent history” LedgerHashes object
• A number of “previous history” LedgerHashes objects based on the current ledger index. Specifically, the XRP Ledger adds a new “previous history” object every 65536 ledger versions.

Fields

common_fields: CommonFields<'a, NoFlags>

The base fields for all ledger object models.

See Ledger Object Common Fields: <https://xrpl.org/ledger-entry-common-fields.html>

first_ledger_sequence: u32

DEPRECATED Do not use.

hashes: Vec<Cow<'a, str>>

An array of up to 256 ledger hashes. The contents depend on which sub-type of LedgerHashes object this is.

last_ledger_sequence: u32

The Ledger Index of the last entry in this object’s Hashes array.

Implementations

impl<'a> LedgerHashes<'a>

pub fn new( index: Option<Cow<'a, str>>, ledger_index: Option<Cow<'a, str>>, first_ledger_sequence: u32, hashes: Vec<Cow<'a, str>>, last_ledger_sequence: u32, ) -> Self

Trait Implementations

impl<'a> Clone for LedgerHashes<'a>

fn clone(&self) -> LedgerHashes<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for LedgerHashes<'a>

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

Formats the value using the given formatter.

impl<'de, 'a> Deserialize<'de> for LedgerHashes<'a>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> LedgerObject<NoFlags> for LedgerHashes<'a>

fn get_ledger_entry_type(&self) -> LedgerEntryType

fn has_flag(&self, flag: &T) -> bool

impl<'a> Model for LedgerHashes<'a>

fn get_errors(&self) -> XRPLModelResult<()>

Collects a models errors and returns the first error that occurs.

fn validate(&self) -> XRPLModelResult<()>

Simply forwards the error from get_errors if there was one.

fn is_valid(&self) -> bool

Checks if the model is valid.

impl<'a> PartialEq for LedgerHashes<'a>

fn eq(&self, other: &LedgerHashes<'a>) -> bool

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Serialize for LedgerHashes<'a>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
