Struct Parser 

pub struct Parser { /* private fields */ }

High-performance parser using Node architecture (16 bytes/node). This is the optimized path for Phase 8 test suite evaluation.

Implementations

impl Parser

Trait Implementations

impl From<Parser> for JsValue

fn from(value: Parser) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Parser

type Abi = u32

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

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for Parser

type Abi = u32

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

fn into_abi(self) -> u32

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

impl LongRefFromWasmAbi for Parser

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Parser>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Parser

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 Parser

fn none() -> Self::Abi

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

impl RefFromWasmAbi for Parser

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Parser>

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
