Expand description

The parser maintains two input streams: one for input from script through document.write(), and one for input from network.

There is no concrete representation of the insertion point, instead it always points to just before the next character from the network input, with all of the script input before itself.

    ... script input ... | ... network input ...
                         ^
                insertion point

Fields

reflector: Reflectordocument: Dom<Document>

The document associated with this parser.

bom_sniff: DomRefCell<Option<Vec<u8>>>

The BOM sniffing state.

None means we’ve found the BOM, we’ve found there isn’t one, or we’re not parsing from a byte stream. Some contains the BOM bytes found so far.

network_decoder: DomRefCell<Option<NetworkDecoder>>

The decoder used for the network input.

network_input: DomRefCell<BufferQueue>

Input received from network.

script_input: DomRefCell<BufferQueue>

Input received from script. Used only to support document.write().

tokenizer: DomRefCell<Tokenizer>

The tokenizer of this parser.

last_chunk_received: Cell<bool>

Whether to expect any further input from the associated network request.

suspended: Cell<bool>

Whether this parser should avoid passing any further data to the tokenizer.

script_nesting_level: Cell<usize>

https://html.spec.whatwg.org/multipage/#script-nesting-level

aborted: Cell<bool>

https://html.spec.whatwg.org/multipage/#abort-a-parser

script_created_parser: bool

https://html.spec.whatwg.org/multipage/#script-created-parser

prefetch_tokenizer: DomRefCell<Tokenizer>

We do a quick-and-dirty parse of the input looking for resources to prefetch.

prefetch_input: DomRefCell<BufferQueue>

Implementations

Corresponds to the latter part of the “Otherwise” branch of the ‘An end tag whose tag name is “script”’ of https://html.spec.whatwg.org/multipage/#parsing-main-incdata

This first moves everything from the script input to the beginning of the network input, effectively resetting the insertion point to just before the next character to be consumed.

    | ... script input ... network input ...
    ^
    insertion point

Steps 6-8 of https://html.spec.whatwg.org/multipage/#document.write()

Trait Implementations

Returns the receiver’s reflector.

Returns the global scope of the realm that the DomObject was created in.

Function pointer to the general wrap function type

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

Returns whether the given DOM class derives that interface.

Trace self.
