Kinds of QueryError.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

The query is empty or only whitespace.

UnexpectedEnd

The query ended where expected was required.

Fields

expected: &'static str

What the parser was looking for.

UnexpectedToken

A token appeared where expected was required.

Fields

found: String

The offending token text.

expected: &'static str

What the parser was looking for.

UnterminatedString

A quoted string has no closing quote.

LoneOperator(char)

A single & or |.

UnknownField(String)

A word followed by an operator that is not a known field.

ExpectedNumber

The field takes a number (children, depth).

InvalidOperator

The operator is not valid for this field (e.g. children ~ 2).

EmptyPath

An empty segment in a dotted path (attrs., attrs..x).
