Trait jemalloc_ctl::Access

pub trait Access<T> {
    fn read(&self) -> Result<T>;
    fn write(&self, value: T) -> Result<()>;
    fn update(&self, value: T) -> Result<T>;
}

Safe read access to the MALLCTL NAMESPACE.

Required methods

fn read(&self) -> Result<T>

Read the key at self.

fn write(&self, value: T) -> Result<()>

Write value at the key self.

fn update(&self, value: T) -> Result<T>

Write value at the key self returning its previous value.
