Methods

impl Expression

fn minimum(&self) -> Option<i32>

Returns the smallest possible result of rolling this dice rolling expression.

fn maximum(&self) -> Option<i32>

Returns the largest possible result of rolling this dice rolling expression.

fn average(&self) -> Option<Ratio>

Returns the average result of rolling this dice rolling expression.

fn results(&self) -> Option<Vec<i32>>

Returns all the possible results of rolling this dice rolling expression.

fn probabilities(&self) -> Option<Vec<(i32, Ratio)>>

Returns the probabilities of all the possible results of rolling this dice rolling expression.

impl Expression

fn roll(&self, rng: &mut Rng) -> Option<i32>

Rolls this dice rolling expression and returns the result.

This method returns None if any of the binary operations fail (e.g., integer overflow).

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for Expression

fn eq(&self, __arg_0: &Expression) -> bool

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

fn ne(&self, __arg_0: &Expression) -> bool

This method tests for !=.
