# Structs
ComparisonExpr represents the comparison of two values, which themselves may be the output of expressions.
ExistExpr represents an existence expression.
FilterQueryExpr represents a JSONPath Query used in a filter expression.
FilterSelector is a filter selector, e.g., ?().
FunctionExpr represents a function expression, consisting of a named function and its arguments.
LiteralArg represents a literal JSON value, excluding objects and arrays.
LocatedNode pairs a value with its location within the JSON query argument from which it was selected.
NonExistExpr represents a nonexistence expression.
NotFuncExpr represents a "!func()" expression.
NotParenExpr represents a parenthesized expression preceded with a !.
ParenExpr represents a parenthesized expression.
PathQuery represents a JSONPath expression.
Segment represents a single segment in an RFC 9535 JSONPath query, consisting of a list of Selectors and child Segments.
SingularQueryExpr represents a query that produces a single node (JSON value), or nothing.
SliceSelector is a slice selector, e.g., [0:100:5].
ValueType encapsulates a JSON value, which should be a string, integer, float, nil, true, false, []any, or map[string]any.
WildcardSelector is the underlying nil value used by [Wildcard].
# Interfaces
BasicExpr defines the interface for filter expressions.
