Struct ExtensionParser

pub struct ExtensionParser {
    state: ExtensionParserState,
    extensions: SimpleExtensions,
}

The parser for the extension section of the Substrait file format.

This is responsible for parsing the extension section of the file, which contains the extension URIs and declarations. Note that this parser does not parse the header; otherwise, this is symmetric with the SimpleExtensions::write method.

Fields

state: ExtensionParserState

extensions: SimpleExtensions
