Enum BankSnapshotKind

pub enum BankSnapshotKind {
    Pre,
    Post,
}

Bank snapshots traditionally had their accounts hash calculated prior to serialization. Since the hash calculation takes a long time, an optimization has been put in to offload the accounts hash calculation. The bank serialization format has not changed, so we need another way to identify if a bank snapshot contains the calculated accounts hash or not.

When a bank snapshot is first taken, it does not have the calculated accounts hash. It is said that this bank snapshot is “pre” accounts hash. Later, when the accounts hash is calculated, the bank snapshot is re-serialized, and is now “post” accounts hash.

Variants

Pre

This bank snapshot has not yet had its accounts hash calculated

Post

This bank snapshot has had its accounts hash calculated

Trait Implementations

impl Clone for BankSnapshotKind

fn clone(&self) -> BankSnapshotKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BankSnapshotKind

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

Formats the value using the given formatter.

impl PartialEq for BankSnapshotKind

fn eq(&self, other: &BankSnapshotKind) -> 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.
