Struct solana_runtime::accounts_hash::AccountHashesFile

source · 
pub struct AccountHashesFile {
    count_and_writer: Option<(usize, BufWriter<File>)>,
}
Expand description

1 file containing account hashes sorted by pubkey

Fields§

§count_and_writer: Option<(usize, BufWriter<File>)>

hashes and an open file that will be deleted on drop. None if there are zero hashes to represent, and thus, no file.

Implementations§

source§

impl AccountHashesFile

source

fn get_reader(&mut self) -> Option<(usize, MmapAccountHashesFile)>

map the file into memory and return a reader that can access it by slice

source

pub fn count(&self) -> usize

hashes stored in this file
source

pub fn write(&mut self, hash: &Hash)

write ‘hash’ to the file If the file isn’t open, create it first.
