Struct LayoutTreeIR 

pub struct LayoutTreeIR {
    pub schema_version: u32,
    pub root: LayoutNode,
}

Top-level IR document.

Fields

schema_version: u32

Schema version of this IR document. See SCHEMA_VERSION.

root: LayoutNode

Root layout node.

Implementations

impl LayoutTreeIR

pub fn new() -> Self

Build an empty IR rooted at a Root node.

pub fn to_canonical_json(&self) -> String

Render this IR to a canonical, deterministic JSON string.

See canonical_json for the formatting contract.

pub fn node_count(&self) -> usize

Total number of nodes in the tree, including the root.

Trait Implementations

impl Clone for LayoutTreeIR

fn clone(&self) -> LayoutTreeIR

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutTreeIR

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

Formats the value using the given formatter.

impl Default for LayoutTreeIR

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for LayoutTreeIR

fn eq(&self, other: &LayoutTreeIR) -> 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.
