Variants

WHITESPACE

This rule defines a whitespace character, which can be a space, tab, or newline.

name

This rule defines a sequence of ASCII alphanumeric characters (letters and digits) for names.

number

This rule defines a number, which can either be an integer or a floating-point number without the decimal part.

vehicle

This rule defines the structure of a vehicle, consisting of brand, model, year, class, engine details, dimensions, max speed, and acceleration.

brand

This rule defines the brand of the vehicle, which is prefixed by “Brand:” followed by a whitespace and the name.

model

This rule defines the model of the vehicle, which is prefixed by “Model:” followed by a whitespace and the name.

year

This rule defines the year of the vehicle, which is prefixed by “Year:” followed by a whitespace and a number.

class

This rule defines the class of the vehicle, which is prefixed by “Class:” followed by a whitespace and the name.

engine

This rule defines the engine details of the vehicle, which starts with “Engine: (” followed by volume, power, and type in the specified format.

volume

This rule defines the volume of the engine, which is prefixed by “Volume:” followed by a whitespace, a number, and the “L” unit.

power

This rule defines the power of the engine, which is prefixed by “Power:” followed by a whitespace, a number, and the “kW” unit.

engine_type

This rule defines the engine type, which is prefixed by “Type:” followed by a whitespace and one of the allowed engine types: Petrol, Diesel, or Electric.

engine_type_inner

This rule defines the allowed engine types: Petrol, Diesel, or Electric.

dimensions

This rule defines the dimensions of the vehicle, which are prefixed by “Dimensions:” followed by a whitespace and three numbers representing length, width, and height in the format “length x width x height mm”.

max_speed

This rule defines the maximum speed of the vehicle, which is prefixed by “Max speed:” followed by a whitespace, a number, and the “km/h” unit.

acceleration

This rule defines the acceleration of the vehicle, which is prefixed by “Acceleration:” followed by a whitespace, a number, and the text “s to 100 km/h”.

Implementations

impl Rule

pub fn all_rules() -> &'static [Rule]

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl Hash for Rule

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 Ord for Rule

fn cmp(&self, other: &Rule) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl Parser<Rule> for VehicleParser

fn parse<'i>(rule: Rule, input: &'i str) -> Result<Pairs<'i, Rule>, Error<Rule>>

Parses a &str starting from rule.

impl PartialEq for Rule

fn eq(&self, other: &Rule) -> 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 PartialOrd for Rule

fn partial_cmp(&self, other: &Rule) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
