Struct ViewDef 

pub struct ViewDef<'a> {
    pub component: Option<Symbol>,
    pub root: ViewRoot<'a>,
    pub nodes: Vec<ViewNode<'a>>,
    pub mentions: Vec<(Symbol, Span)>,
    pub span: Span,
}

One complete view: a Render: block, a Render into <el>: block, or a component’s View: — in source order they appear in crate::parser::Parser::views.

Fields

component: Option<Symbol>

The component this view belongs to (None for a bare Render:).

root: ViewRoot<'a>

Where the tree renders.

nodes: Vec<ViewNode<'a>>

mentions: Vec<(Symbol, Span)>

Every identifier the template MENTIONS, with its span in the FILE.

★ THE ONE THING A TOKEN WALK CANNOT RECOVER. A View: body reaches the parser as a single RawBlock token, so a name used only in a template is not in the token stream at all — which is why an editor could not jump from {count} to the Let count be 0. it names, the most common movement there is in an LGX file. The positions are known HERE and only here: TExpr carries its offset in the template body, and the parser holds the map from body offsets to file offsets. Recorded on the way past rather than re-derived, because a second copy of that arithmetic is a second thing to get wrong.

span: Span

Implementations

impl<'a> ViewDef<'a>

pub fn exprs_and_blocks(&self) -> (Vec<&'a Expr<'a>>, Vec<Block<'a>>)

Every expression and every statement block the tree references (holes, attribute values, conditions, iterables, keys, handler bodies) — the traversal surface for depth bounds, scope analysis and tooling walks.

pub fn shape(&self, interner: &Interner) -> String

A compact, deterministic one-line rendering of the tree — the snapshot surface view_ir_lock pins and largo expand prints.

pub fn body_shape(&self, interner: &Interner) -> String

Just the node tree, without the view of <Name> head — what a component’s own shape embeds.

Trait Implementations

impl<'a> Clone for ViewDef<'a>

fn clone(&self) -> ViewDef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ViewDef<'a>

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

Formats the value using the given formatter.
