Variants

Id

Identity, i.e. .

Num(String)

Integer or floating-point number.

Str(String)

String

Var(String)

Variable, such as $x (without leading ‘$’)

Array(Option<Box<Spanned<Self>>>)

Array, empty if None

Object(Vec<KeyVal>)

Object, specifying its key-value pairs

Path(Box<Spanned<Self>>, Path<Self>)

Path such as ., .a, .[][]."b"

If(Vec<(Spanned<Self>, Spanned<Self>)>, Box<Spanned<Self>>)

If-then-else

Reduce(Fold<Box<Spanned<Self>>>)

Reduction, e.g. reduce .[] as $x (0; .+$x)

Foreach(Fold<Box<Spanned<Self>>>, Option<Box<Spanned<Self>>>)

Reduction returning intermediate results

Call(String, Vec<Spanned<Self>>)

Call to another filter, e.g. map(.+1)

Try(Box<Spanned<Self>>)

Error suppression, e.g. keys?

Neg(Box<Spanned<Self>>)

Negation

Recurse

Recursion (..)

Binary(Box<Spanned<Self>>, BinaryOp, Box<Spanned<Self>>)

Binary operation, such as 0, 1, [] | .[], .[] += 1, 0 == 0, …
