Trait Implementations

impl Clone for LedgerSnapshot

fn clone(&self) -> LedgerSnapshot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LedgerSnapshot

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

Formats the value using the given formatter.

impl Default for LedgerSnapshot

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LedgerSnapshot

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<LedgerSnapshot> for LedgerSnapshot

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for LedgerSnapshot

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

Serialize this value into the given Serde serializer.

impl SnapshotSource for &LedgerSnapshot

fn get(&self, key: &LedgerKey) -> Result<LedgerEntry, HostError>

fn has(&self, key: &LedgerKey) -> Result<bool, HostError>

impl SnapshotSource for LedgerSnapshot

fn get(&self, key: &LedgerKey) -> Result<LedgerEntry, HostError>

fn has(&self, key: &LedgerKey) -> Result<bool, HostError>
