pub struct Log<'a, S, T> {
    pub state: &'a mut LogState,
    /* private fields */
}

A generic log parameterized by its storage type S and log entry type T.

Fields

state: &'a mut LogState

Implementations

impl<'a, S: StorageStack, T> Log<'a, S, T>

pub fn new(state: &'a mut LogState, storage: &'a mut S) -> Self

Return Log by initializing it with a LogState and a StorageStack.

pub fn push(&mut self, entry: T) -> Option<()>

where T: ArgumentEncoder,

Add a new entry to the log. Return None if the log is full, or storage is full.

pub fn size(&self) -> u64

Return number of entries in the log.

pub fn get(&self, index: u64) -> Option<T>

where T: for<'de> ArgumentDecoder<'de>,

Look up a log entry by index. Return None if the index is out of range, or it fails to read the entry.
