Trait LogScanner 

Source 
pub trait LogScanner: Send {
    // Required method
    fn next_entry(&mut self, from_vlsn: u64) -> Option<(u64, u8, Vec<u8>)>;
}
Expand description

An iterator over log entries starting from a given VLSN.

Corresponds to FeederSource / MasterFeederSource. The scanner returns (vlsn, entry_type, payload) tuples in VLSN order. Returning None signals that there are no more entries yet; the caller will call next_entry again after a short wait.

Required Methods§

Source

fn next_entry(&mut self, from_vlsn: u64) -> Option<(u64, u8, Vec<u8>)>

Return the next available entry with VLSN >= from_vlsn, or None if no new entry is available at this moment.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
