Struct solana_runtime::in_mem_accounts_index::FlushGuard

struct FlushGuard<'a> {
    flushing: &'a AtomicBool,
}

An RAII implementation of a scoped lock for the flushing_active atomic flag in InMemAccountsIndex. When this structure is dropped (falls out of scope), the flag will be cleared (set to false).

After successfully locking (calling FlushGuard::lock()), pass a reference to the FlashGuard instance to any function/code that requires the flushing_active flag has been set (to true).

Fields

flushing: &'a AtomicBool

Implementations

impl<'a> FlushGuard<'a>

fn lock(flushing: &'a AtomicBool) -> Option<Self>

Set the flushing atomic flag to true. If the flag was already true, then return None (so as to not clear the flag erroneously). Otherwise return Some(FlushGuard).

Trait Implementations

impl<'a> Debug for FlushGuard<'a>

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

Formats the value using the given formatter.

impl Drop for FlushGuard<'_>

fn drop(&mut self)

Executes the destructor for this type.
