Enum ElementSelector 

pub enum ElementSelector {
    Branch(bool),
    Block(usize),
}

Selects a child Element within an Element. The selector must match the parent type.

Variants

Branch(bool)

Selects between the true and false paths of a Branch.

Block(usize)

Indexes into the children of a Block.

Implementations

impl ElementSelector

pub fn as_path(&self) -> &ElementPath

Get this ElementSelector as an ElementPath slice.

pub fn as_mut_path(&mut self) -> &mut ElementPath

Get this ElementSelector as a mut ElementPath slice.

pub fn unwrap_branch(self) -> bool

Gets the branch boolean or panics.

pub fn unwrap_block(self) -> usize

Gets the block index or panics.

pub fn unwrap_branch_mut(&mut self) -> &mut bool

Mutably gets the branch boolean or panics.

pub fn unwrap_block_mut(&mut self) -> &mut usize

Mutably gets the block index or panics.

Trait Implementations

impl Borrow<ElementPath> for ElementSelector

fn borrow(&self) -> &ElementPath

Immutably borrows from an owned value.

impl BorrowMut<ElementPath> for ElementSelector

fn borrow_mut(&mut self) -> &mut ElementPath

Mutably borrows from an owned value.

impl Clone for ElementSelector

fn clone(&self) -> ElementSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElementSelector

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

Formats the value using the given formatter.

impl ElementIndex for ElementSelector

type PathSelectors = Once<ElementSelector>

fn path_selectors(self) -> Self::PathSelectors

impl From<bool> for ElementSelector

fn from(cond: bool) -> Self

Converts to this type from the input type.

impl From<usize> for ElementSelector

fn from(index: usize) -> Self

Converts to this type from the input type.

impl Hash for ElementSelector

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 ElementSelector

fn cmp(&self, other: &ElementSelector) -> 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 ElementSelector

fn eq(&self, other: &ElementSelector) -> 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 ElementSelector

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