FreshnessClock

evm_fork_cache::freshness

Trait FreshnessClock 

Source 
pub trait FreshnessClock: Send + Sync {
    // Required method
    fn now(&self) -> u64;

    // Provided method
    fn advance(&self, _now: u64) { ... }
}
Expand description

Source of the current clock value used throughout the freshness model.

Implementations return a monotone-ish u64 in their own units. The two built-ins are BlockClock (block number, the default) and WallClock (unix seconds).

Required Methods§

Source

fn now(&self) -> u64

The current clock value (block number or unix seconds).

Provided Methods§

Source

fn advance(&self, _now: u64)

Advance the clock to now.

Called by FreshnessController::on_new_block so the natural API drives the clock forward. The default is a no-op (for clocks like WallClock that advance on their own); BlockClock overrides it to set the block.

Dyn Compatibility§

This trait is dyn compatible.

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