Struct Environment

pub struct Environment {
    pub random: Arc<dyn Random>,
    pub quota: Option<Arc<dyn Quota>>,
    pub parallelism: Parallelism,
    pub logger: Arc<dyn Fn(&str) + Send + Sync>,
    pub is_experimental: bool,
}

Keeps track of environment specific information which influences algorithm behavior.

Fields

random: Arc<dyn Random>

A wrapper on random generator.

quota: Option<Arc<dyn Quota>>

A global execution quota.

parallelism: Parallelism

Keeps data parallelism settings.

logger: Arc<dyn Fn(&str) + Send + Sync>

An information logger.

is_experimental: bool

A boolean flag which signalizes that experimental behavior is allowed.

Implementations

impl Environment

pub fn new_with_time_quota(max_time: Option<usize>) -> Environment

Creates an instance of Environment using optional time quota and defaults.

pub fn new( random: Arc<dyn Random>, quota: Option<Arc<dyn Quota>>, parallelism: Parallelism, logger: Arc<dyn Fn(&str) + Send + Sync>, is_experimental: bool, ) -> Environment

Creates an instance of Environment.
