Trait Function 

pub trait Function: Sync + Send {
    // Required method
    fn call(&self, args: &HashMap<String, Value>) -> Result<Value, Error>;

    // Provided method
    fn is_safe(&self) -> bool { ... }
}

The global function type definition

Required Methods

fn call(&self, args: &HashMap<String, Value>) -> Result<Value, Error>

The global function type definition

Provided Methods

fn is_safe(&self) -> bool

Whether the current function’s output should be treated as safe, defaults to false

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
