Struct StoredMeta

#[repr(C)]
pub struct StoredMeta {
    pub write_version_obsolete: StoredMetaWriteVersion,
    pub data_len: u64,
    pub pubkey: Pubkey,
}

Meta contains enough context to recover the index from storage itself This struct will be backed by mmaped and snapshotted data files. So the data layout must be stable and consistent across the entire cluster!

Fields

write_version_obsolete: StoredMetaWriteVersion

global write version This will be made completely obsolete such that we stop storing it. We will not support multiple append vecs per slot anymore, so this concept is no longer necessary. Order of stores of an account to an append vec will determine ‘latest’ account data per pubkey.

data_len: u64

pubkey: Pubkey

key for the account

Trait Implementations

impl Clone for StoredMeta

fn clone(&self) -> StoredMeta

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StoredMeta

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for StoredMeta

fn eq(&self, other: &StoredMeta) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
