Struct ObjectView 

pub struct ObjectView<'a> { /* private fields */ }

Borrowed view over an object (JSONParser.h:239 JSONObject). Grown in B3 with name lookups + iteration.

Implementations

impl<'a> ObjectView<'a>

pub fn size(&self) -> usize

Number of members (faithful to C++ JSONObject::size).

pub fn get_hidden_class(&self) -> &'a JSONHiddenClass<'a>

Returns the hidden class descriptor shared among same-shape objects.

pub fn get(&self, name: &str, atoms: &AtomTable) -> Option<&'a JSONValue<'a>>

JSONParser.h:286 — value for name, or None.

pub fn at(&self, name: &str, atoms: &AtomTable) -> &'a JSONValue<'a>

JSONParser.h:295 — value for name; panics if absent (C++ asserts).

pub fn count(&self, name: &str, atoms: &AtomTable) -> usize

JSONParser.h:323 — 1 if present else 0.

pub fn value_at(&self, index: usize) -> &'a JSONValue<'a>

Value by position (0..size). Panics if out of range.

pub fn key_at(&self, index: usize) -> AtomBytes

Key (interned handle) by position. Panics if out of range.

pub fn find(&self, name: &str, atoms: &AtomTable) -> Option<usize>

JSONParser.h:440 — index of name in the (sorted) members, or None. (C++ returns an iterator; we return the positional index for use with value_at/key_at.)

pub fn iter(&self) -> impl Iterator<Item = (AtomBytes, &'a JSONValue<'a>)> + '_

JSONParser.h:330 — (key, value) pairs, in the hidden class’s sorted order.
