Def

Struct Def 

Source
pub struct Def<S = &'static str, F = Term<S>> {
    pub name: S,
    pub args: Vec<S>,
    pub body: F,
}
Expand description

jq definition, consisting of a name, optional arguments, and a body.

Examples:

def pi: 3.1415;
def double($x): $x + $x;
def map(f): [.[] | f];
def recurse(f; cond): recurse(f | select(cond));

Fields§

§name: S

name, e.g. "double" or "map"

§args: Vec<S>

arguments, e.g. ["$x"], ["f"], or ["f", "cond"]

§body: F

right-hand side, e.g. a term corresponding to [.[] | f]
