Struct ExecutionPolicy 

pub struct ExecutionPolicy { /* private fields */ }

Process-wide execution planning policy.

Examples

use tenferro_runtime::{Determinism, ExecutionPolicy};

let policy = ExecutionPolicy::new(Determinism::Fast, Some(1024), 7);
assert_eq!(policy.hard_workspace_limit_bytes(), Some(1024));

Implementations

impl ExecutionPolicy

pub fn new( determinism: Determinism, hard_workspace_limit_bytes: Option<usize>, planning_seed: u64, ) -> Self

Build an execution policy.

Examples

use tenferro_runtime::{Determinism, ExecutionPolicy};

let policy = ExecutionPolicy::new(Determinism::Reproducible, None, 0);
assert_eq!(policy.determinism(), Determinism::Reproducible);

pub fn determinism(&self) -> Determinism

Return the determinism mode.

Examples

use tenferro_runtime::{Determinism, ExecutionPolicy};

assert_eq!(
    ExecutionPolicy::new(Determinism::Fast, None, 0).determinism(),
    Determinism::Fast
);

pub fn hard_workspace_limit_bytes(&self) -> Option<usize>

Return the hard workspace limit in bytes, if one is configured.

Examples

use tenferro_runtime::{Determinism, ExecutionPolicy};

assert_eq!(
    ExecutionPolicy::new(Determinism::Fast, Some(8), 0).hard_workspace_limit_bytes(),
    Some(8)
);

pub fn planning_seed(&self) -> u64

Return the planning seed.

Examples

use tenferro_runtime::{Determinism, ExecutionPolicy};

assert_eq!(ExecutionPolicy::new(Determinism::Fast, None, 42).planning_seed(), 42);

Trait Implementations

impl Clone for ExecutionPolicy

fn clone(&self) -> ExecutionPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecutionPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ExecutionPolicy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExecutionPolicy

fn eq(&self, other: &ExecutionPolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
