Trait RssSource 

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

    // Provided method
    fn total_ram_bytes(&self) -> u64 { ... }
}
Expand description

Abstraction over “what is the current process RSS, in bytes”.

Implementations may cache their reading; the budget calls RssSource::read_rss_bytes once per tick and is happy with a best-effort value.

Required Methods§

Source

fn read_rss_bytes(&self) -> u64

Current process RSS in bytes.

Provided Methods§

Source

fn total_ram_bytes(&self) -> u64

Installed system RAM in bytes. Used at startup when auto-deriving the budget target. Implementations must return a positive value.

Dyn Compatibility§

This trait is dyn compatible.

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