JsRunScriptWithParserState

Deserializes the cache of initial parser state and (along with the same script source) executes the script and returns the result.

Syntax

CHAKRA_API
    JsRunScriptWithParserState(
        _In_ JsValueRef script,
        _In_ JsSourceContext sourceContext,
        _In_ JsValueRef sourceUrl,
        _In_ JsParseScriptAttributes parseAttributes,
        _In_ JsValueRef parserState,
        _Out_ JsValueRef * result);

Parameters

• script: The script to run.
• sourceContext: A cookie identifying the script that can be used by debuggable script contexts.
• sourceUrl: The location the script came from
• parseAttributes: Attribute mask for parsing the script
• parserState: A buffer containing a cache of the parser state generated by JsSerializeParserState.
• result: The result of the script, if any. This parameter can be null.

Return Value

The code JsNoError if the operation succeeded, a failure code otherwise.

Remarks

This API is experimental and may have breaking changes later.

Requires an active script context. Script source can be either JavascriptString or JavascriptExternalArrayBuffer. In case it is an ExternalArrayBuffer, and the encoding of the buffer is Utf16, JsParseScriptAttributeArrayBufferIsUtf16Encoded is expected on parseAttributes. Use JavascriptExternalArrayBuffer with Utf8/ASCII script source for better performance and smaller memory footprint.
