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"

§

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

If-then-else

§

Fold(FoldType, Fold<Box<Spanned<Self>>>)

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

The first field indicates whether to yield intermediate results (false for reduce and true for foreach).

§

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, …
