Trait VerbArgument

pub trait VerbArgument: Clone {
    // Required method
    fn from_value(value: &KdlEntry) -> Option<Self>;

    // Provided method
    fn get_error_type_name() -> &'static str { ... }
}

A type that can be used as an argument of Verbs and Conditions

Required Methods

fn from_value(value: &KdlEntry) -> Option<Self>

Convert from a KdlEntry to the value

Implementations are free to accept more than a single way of interpreting values. E.g. a string and a integer.

Provided Methods

fn get_error_type_name() -> &'static str

A human-readable typename

This is shown only in error-messages

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
