}

indicates all possible errors during parsing

Variants

IO(Error)

wrap system IO errors, usually an open error when opening the given path

UnexpectedToken

Fields

path: Option<PathBuf>

location: (usize, usize)

expect: Vec<TokenKind>

actual: Option<Token>

syntax error such as some token are not in the right position

Else

Fields

path: Option<PathBuf>

location: (usize, usize)

reason: String

some other parser errors include scanner errors such as parsing numeric literal errors
