Struct solana_snapshot_etl::append_vec::AppendVec

pub struct AppendVec { /* private fields */ }

A thread-safe, file-backed block of memory used to store Account instances. Append operations are serialized such that only one thread updates the internal append_lock at a time. No restrictions are placed on reading. That is, one may read items from one thread while another is appending new items.

Implementations

impl AppendVec

pub fn remaining_bytes(&self) -> u64

how many more bytes can be stored in this append vec

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> u64

pub fn new_from_file<P: AsRef<Path>>(path: P, current_len: usize) -> Result<Self>

pub fn new_from_reader<R: Read>(
    reader: &mut R,
    current_len: usize
) -> Result<Self>

pub fn get_account<'a>(
    &'a self,
    offset: usize
) -> Option<(StoredAccountMeta<'a>, usize)>

Return account metadata for the account at offset if its data doesn’t overrun the internal buffer. Otherwise return None. Also return the offset of the first byte after the requested data that falls on a 64-byte boundary.
