Struct Decl 

pub struct Decl {
    pub parent: Option<usize>,
    pub construct: &'static str,
    pub name: Option<String>,
    pub traits: &'static [&'static str],
    pub kind: String,
    pub span: (usize, usize),
    pub lines: (usize, usize),
    pub signature: Option<String>,
    pub doc: Option<String>,
    pub callee: Option<String>,
    pub n_params: Option<i64>,
}

One lowered construct — the code level’s producer seam, the parallel of quarb_text::Block. A producer emits Decls in pre-order (a parent precedes its children); CodeModel::build derives the arbor. The tree-sitter producer lives in this crate; another backend supplies the same stream and nothing above it moves.

Fields

parent: Option<usize>

Index of the parent Decl, or None for a top-level one.

construct: &'static str

The vocabulary word: function, type, if, call, …

name: Option<String>

The declared (or adopted) identifier, where one exists.

traits: &'static [&'static str]

Curated trait set — never backend kinds.

kind: String

The raw backend kind; surfaces only as ::::kind.

span: (usize, usize)

Byte range into the source.

lines: (usize, usize)

1-based start/end lines.

signature: Option<String>

The declaration head, whitespace-collapsed (::signature).

doc: Option<String>

Attached documentation, markers stripped (::doc).

callee: Option<String>

A call’s callee text (::callee).

n_params: Option<i64>

Declared parameter count, functions only (::::n-params).

Trait Implementations

impl Debug for Decl

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

Formats the value using the given formatter.
