Struct JSONFactory 

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

Owns all JSON nodes (in the arena), uniques strings/numbers, and shares hidden classes. Port of JSONFactory (JSONParser.h:524). Accessors take &self; the returned &'a JSONValue lives in the arena, independent of the transient RefCell borrow, so a caller may interleave factory use with parsing (as JSONParserTest::SmokeTest2 does).

Implementations

impl<'a> JSONFactory<'a>

pub fn new(arena: &'a Bump, atoms: &'a AtomTable) -> JSONFactory<'a>

Create a new factory backed by arena and atoms.

pub fn arena(&self) -> &'a Bump

Returns the arena backing this factory.

pub fn atoms(&self) -> &'a AtomTable

Returns the atom table used by this factory.

pub fn get_null(&self) -> &'a JSONValue<'a>

Returns the singleton null value.

pub fn get_boolean(&self, v: bool) -> &'a JSONValue<'a>

Returns the singleton boolean value for v.

pub fn get_string(&self, lit: AtomBytes) -> &'a JSONValue<'a>

JSONParser.cpp:79 — unique a string by its interned handle.

pub fn get_string_str(&self, s: &str) -> &'a JSONValue<'a>

JSONParser.cpp:92 — intern str then unique.

pub fn get_number(&self, value: f64) -> &'a JSONValue<'a>

JSONParser.cpp:96 — unique a number by its bit pattern (so -0.0 != 0.0, matching JSONNumber::Profile using DoubleToBits).

pub fn sort_props(&self, props: &mut [Prop<'a>]) -> Option<AtomBytes>

JSONParser.cpp:120 — sort props by key content; return the first duplicate key (by interned identity) if any, else None.

pub fn get_hidden_class(&self, keys: &[AtomBytes]) -> &'a JSONHiddenClass<'a>

JSONParser.cpp:109 — look up or create the shared hidden class for keys (already content-sorted).

pub fn new_object(&self, props: &mut [Prop<'a>]) -> Option<&'a JSONValue<'a>>

JSONParser.cpp:138 — create an object from props. Sorts + dedups; returns None on a duplicate key.

pub fn new_object_sorted(&self, props: &[Prop<'a>]) -> Option<&'a JSONValue<'a>>

JSONParser.cpp:138 with propsAreSorted=true — props already sorted and dup-checked.

pub fn new_array(&self, values: &[&'a JSONValue<'a>]) -> &'a JSONValue<'a>

JSONParser.h:617 — create an array from values.
