pub struct CustomFunction { /* private fields */ }

Expand description

Custom function that allows the creation of runtime functions with signature validation.

Implementations

source

impl CustomFunction

source

pub fn new(
fn_signature: Signature,
f: Box<dyn Fn(&[Rcvar ], &mut Context<'_>) -> Result<Rcvar, JmespathError> + Sync>
) -> CustomFunction

Creates a new custom function.

Trait Implementations

impl Function for CustomFunction

source

fn evaluate(
 &self,
 args: &[Rcvar ],
 ctx: &mut Context<'_>
) -> Result<Rcvar, JmespathError>

Evaluates the function against an in-memory variable.
