Trait Implementations

impl Clone for SlotHistory

fn clone(&self) -> SlotHistory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SlotHistory

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

Formats the value using the given formatter.

impl Default for SlotHistory

fn default() -> SlotHistory

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SlotHistory

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SlotHistory

fn eq(&self, other: &SlotHistory) -> 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 SlotHistory

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sysvar for SlotHistory

fn size_of() -> usize

The size in bytes of the sysvar as serialized account data.

fn from_account_info( _account_info: &AccountInfo<'_> ) -> Result<SlotHistory, ProgramError>

Deserializes the sysvar from its AccountInfo.

fn to_account_info(&self, account_info: &mut AccountInfo<'_>) -> Option<()>

Serializes the sysvar to AccountInfo.

fn get() -> Result<Self, ProgramError>

Load the sysvar directly from the runtime.

impl SysvarId for SlotHistory

fn id() -> Pubkey

The Pubkey of the sysvar.

fn check_id(pubkey: &Pubkey) -> bool

Returns true if the given pubkey is the program ID.

impl Eq for SlotHistory

impl StructuralPartialEq for SlotHistory
