Struct LayoutNodeId 

pub struct LayoutNodeId(/* private fields */);

Deterministic identifier for a layout node, derived from its position in the tree (sequence of child indices from the root).

Root has an empty path. The first child of root is "0". The third child of the second child of root is "1/2". The encoding is human-readable and stable across runs and platforms.

Implementations

impl LayoutNodeId

pub fn root() -> Self

The identifier of the tree’s root.

pub fn child(&self, index: usize) -> Self

Derive the identifier of the index-th child of self.

pub fn as_str(&self) -> &str

Borrow the path string. Empty for the root.

Trait Implementations

impl Clone for LayoutNodeId

fn clone(&self) -> LayoutNodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutNodeId

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

Formats the value using the given formatter.

impl Default for LayoutNodeId

fn default() -> LayoutNodeId

Returns the “default value” for a type.

impl Hash for LayoutNodeId

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 LayoutNodeId

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

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

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