Struct WasmDocument 

pub struct WasmDocument { /* private fields */ }

A YAML document with byte-faithful source preservation and path-targeted edits.

Implementations

impl WasmDocument

pub fn new(yaml: &str) -> Result<WasmDocument, JsError>

Parse a YAML string into a lossless Document.

pub fn to_string(&self) -> String

Re-emit the document as a string. Byte-identical to original if no edits.

Bound on the JS side as toString() (the conventional camelCase name) so callers can write doc.toString() and override the default Object.prototype.toString rather than coexist with it.

pub fn replace_span( &mut self, start: usize, end: usize, replacement: &str, ) -> Result<(), JsError>

Replace the bytes at start..end with replacement.

Bound on the JS side as replaceSpan(start, end, replacement) per JS naming conventions.

pub fn get(&self, path: &str) -> Result<JsValue, JsError>

Get the parsed value at a dotted path.

pub fn get_source(&self, path: &str) -> JsValue

Get the raw source fragment at a dotted path.

Bound on the JS side as getSource(path) per JS naming conventions.

pub fn span_at(&self, path: &str) -> Result<JsValue, JsError>

Get the byte range { start, end } for the value at a dotted path.

Bound on the JS side as spanAt(path) per JS naming conventions.

pub fn set_value(&mut self, path: &str, value: JsValue) -> Result<(), JsError>

Set a value at a dotted path using a JS object.

Bound on the JS side as setValue(path, value) per JS naming conventions.

pub fn set(&mut self, path: &str, fragment: &str) -> Result<(), JsError>

Set a value at a dotted path using a YAML fragment string.

pub fn comments_at(&self, path: &str) -> Result<JsValue, JsError>

Read the YAML comments associated with the node at path. Returns { before: string[], inline: string | null } so the caller can surface human-authored doc-comments alongside values — the demo that motivates the entire CST architecture.

Bound on the JS side as commentsAt(path) per JS naming conventions.

impl WasmDocument

pub fn as_document(&self) -> &Document

Native (rlib) accessor for the inner Document. Lets cargo test exercise the underlying state transitions without going through a JS shell.

Trait Implementations

impl From<WasmDocument> for JsValue

fn from(value: WasmDocument) -> Self

Converts to this type from the input type.

impl FromWasmAbi for WasmDocument

type Abi = WasmPtr<WasmRefCell<WasmDocument>>

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for WasmDocument

type Abi = WasmPtr<WasmRefCell<WasmDocument>>

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for WasmDocument

type Abi = WasmPtr<WasmRefCell<WasmDocument>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<WasmDocument>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for WasmDocument

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for WasmDocument

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for WasmDocument

type Abi = WasmPtr<WasmRefCell<WasmDocument>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<WasmDocument>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for WasmDocument

type Abi = WasmPtr<WasmRefCell<WasmDocument>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<WasmDocument>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl SupportsConstructor for WasmDocument

impl SupportsInstanceProperty for WasmDocument

impl SupportsStaticProperty for WasmDocument

impl TryFromJsValue for WasmDocument

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for WasmDocument

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi
