Struct SlotHashesSysvar

source 
pub struct SlotHashesSysvar;
Expand description

API for querying the SlotHashes sysvar.

Implementations§

source§

impl SlotHashesSysvar

source

pub fn get(slot: &Slot) -> Result<Option<Hash>, ProgramError>

Get a value from the sysvar entries by its key. Returns None if the key is not found.

source

pub fn position(slot: &Slot) -> Result<Option<usize>, ProgramError>

Get the position of an entry in the sysvar by its key. Returns None if the key is not found.
