Struct wallet_core::Options

pub struct Options {
    options_range: Range<u8>,
}

options for the vote

currently this is a 4bits structure, allowing up to 16 choices however we may allow more complex object to be set in

Fields

options_range: Range<u8>

Implementations

impl Options

pub fn new_length(num_choices: u8) -> Result<Options, InvalidOptionsLength>

create a new Options with the given number of available choices

available choices will go from 0 to num_choices not included.

pub fn validate(&self, choice: Choice) -> bool

validate the given Choice against the available Options

returns true if the choice is valid, false otherwise. By valid it is meant as in the context of the available Options. There is obviously no wrong choices to make, only lessons to learn.

pub fn choice_range(&self) -> &Range<u8>

Trait Implementations

impl Arbitrary for Options

fn arbitrary<G>(g: &mut G) -> Optionswhere G: Gen,

fn shrink(&self) -> Box<dyn Iterator<Item = Self>, Global>

impl Clone for Options

fn clone(&self) -> Options

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Options

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

Formats the value using the given formatter.

impl PartialEq<Options> for Options

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

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

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

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