§0: SledDbOverlayPtr

Implementations§

source§

impl HeaderStoreOverlay

source

pub fn new(overlay: &SledDbOverlayPtr) -> Result<Self>

source

pub fn insert(&self, headers: &[Header]) -> Result<Vec<HeaderHash>>

Insert a slice of Header into the overlay. The header’s hash() function output is used as the key, while value is the serialized Header itself. On success, the function returns the header hashes in the same order.

source

pub fn get( &self, headerhashes: &[HeaderHash], strict: bool, ) -> Result<Vec<Option<Header>>>

Fetch given headerhashes from the overlay. The resulting vector contains Option, which is Some if the header was found in the overlay, and otherwise it is None, if it has not. The second parameter is a boolean which tells the function to fail in case at least one header was not found.
