Struct smoke::Seed

pub struct Seed(_);

Seed of random generation

There should be only one instance of this for a given instance of a test suite, so that in case of issues, the printed seed of the failed attempt can be re-used as test driven development

All pseudo random generators need to be derived from this

Implementations

impl Seed

pub fn new() -> Self

Create a new random seed, using the system time and the thread-id.

Whilst this is not particularly random, we just need a little randomization not a full blown unguessable entropy. The quality of this randomness is not particularly important or interesting.

Trait Implementations

impl Clone for Seed

fn clone(&self) -> Seed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Seed

impl Debug for Seed

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

Formats the value using the given formatter.

impl Display for Seed

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

Formats the value using the given formatter.

impl Eq for Seed

impl From<u128> for Seed

fn from(u: u128) -> Seed

Performs the conversion.

impl FromStr for Seed

type Err = &'static str

The associated error which can be returned from parsing.

fn from_str(str: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq<Seed> for Seed

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
