Struct twiggy_ir::Id

pub struct Id(_, _);

Methods

impl Id

pub fn section(section: usize) -> Id

Create an Id for a the given section.

pub fn entry(section: usize, index: usize) -> Id

Create an Id for a given entry in a given section.

pub fn root() -> Id

Create the Id for the "meta root".

pub fn serializable(self) -> u64

Trait Implementations

impl PartialOrd<Id> for Id

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl PartialEq<Id> for Id

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

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

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

This method tests for !=.

impl Ord for Id

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl Copy for Id

impl Clone for Id

fn clone(&self) -> Id

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for Id

impl Hash for Id

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, 

Feeds a slice of this type into the given [Hasher].

impl Index<Id> for Items

type Output = Item

The returned type after indexing.

fn index(&self, id: Id) -> &Item

Performs the indexing (container[index]) operation.

impl Debug for Id

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