Implementations

impl Exercise

pub fn new(children: Vec<Block>) -> Self

Create a new exercise.

pub fn with_number(self, number: impl Into<String>) -> Self

Set the number.

pub fn with_difficulty(self, difficulty: Difficulty) -> Self

Set difficulty.

pub fn with_points(self, points: u32) -> Self

Set points.

pub fn with_part(self, part: ExercisePart) -> Self

Add a part.

pub fn with_hint(self, hint: Vec<Block>) -> Self

Add a hint.

pub fn with_solution(self, solution: Solution) -> Self

Set the solution.

Trait Implementations

impl Clone for Exercise

fn clone(&self) -> Exercise

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Exercise

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Exercise

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Exercise

fn eq(&self, other: &Exercise) -> 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.

impl Serialize for Exercise

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
