    ExpectedIdent(u32, u32, String),

Expand description

Errors that can occur during syntactic analysis.

These errors are produced by the parser when the token sequence does not match the expected grammar of EventQL.

Variants§

§

ExpectedIdent(u32, u32, String)

Expected an identifier but found something else.

Fields: (line, column, found_token)

§

ExpectedKeyword(u32, u32, &'static str, String)

Expected a specific keyword but found something else.

Fields: (line, column, expected_keyword, found_token)

§

ExpectedSymbol(u32, u32, Symbol, String)

Expected a specific symbol but found something else.

Fields: (line, column, expected_symbol, found_token)

§

UnexpectedToken(u32, u32, String)

An unexpected token was encountered.

Fields: (line, column, found_token)

This is a general error for tokens that don’t fit the current parse context.

§

UnexpectedEof

The input ended unexpectedly while parsing.

This occurs when the parser expects more tokens but encounters the end of the token stream.
