Trait TraceStorage 

pub trait TraceStorage<C: Copy> {
    const ENABLED: bool;

    // Required methods
    fn new(callsite_info: C) -> Self;
    fn on_contention<E: TransactionHooks<CallsiteInfo = C>>(&self);
    fn on_finalized<E: TransactionHooks<CallsiteInfo = C>>(&self);
    fn set_callsite_info(&self, callsite_info: C);
}

Storage trait for contention spin tracing in ChainLockTransaction.

Required Associated Constants

const ENABLED: bool

Whether contention spin tracing is enabled.

Required Methods

fn new(callsite_info: C) -> Self

Creates a new trace storage instance with the given callsite_info.

fn on_contention<E: TransactionHooks<CallsiteInfo = C>>(&self)

Records the start of contention if not already recorded.

fn on_finalized<E: TransactionHooks<CallsiteInfo = C>>(&self)

Emits the contention trace event if contention occurred during this transaction.

fn set_callsite_info(&self, callsite_info: C)

Updates the callsite info when restarting a transaction.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
