Struct LevelId 

pub struct LevelId {
    pub section: u16,
    pub number: u16,
}

The stable identifier of a level: section.number, such as 1.4 or 10.4.

Identifiers are explicit and never renumbered, so saved games keep working when levels are reordered and the gap at 1.11 stays. Ordering is numeric on (section, number): 1.12 sorts after 1.10, which string comparison would get wrong.

Fields

section: u16

The section number; 0 is the game introduction.

number: u16

The level number within the section; 0 is the section intro.

Implementations

impl LevelId

pub const fn new(section: u16, number: u16) -> Self

Build an identifier from its two parts.

pub const fn is_intro(self) -> bool

True for N.0, the intro page of section N.

pub const fn section_intro(self) -> Self

The intro level of this level’s section.

Trait Implementations

impl Clone for LevelId

fn clone(&self) -> LevelId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LevelId

impl Debug for LevelId

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

Formats the value using the given formatter.

impl Display for LevelId

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

Formats the value using the given formatter.

impl Eq for LevelId

impl FromStr for LevelId

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

Parse S.N where both parts are non-empty ASCII digit strings. Like the Python parse_level_id, leading zeros are accepted ("01.002" is 1.2); anything else, including "1.2.3", "1." and signs, is an error.

type Err = ParseLevelIdError

The associated error which can be returned from parsing.

impl Hash for LevelId

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 LevelId

fn cmp(&self, other: &LevelId) -> 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 PartialEq for LevelId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for LevelId

fn partial_cmp(&self, other: &LevelId) -> 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.
