Trait Command

pub trait Command: Sized {
    type Id: CommandId;
    type Path: CommandPath<Id = Self::Id>;

    // Required methods
    fn parse<I: IntoIterator<Item = S>, S: AsRef<str>>(
        iter: I,
    ) -> Result<Self, CommandParseError>;
    fn id(&self) -> Self::Id;
}

A parsable, identifiable command or family of commands

Required Associated Types

type Id: CommandId

The type of the command ID

type Path: CommandPath<Id = Self::Id>

The type of a valid command path starting at this command

Required Methods

fn parse<I: IntoIterator<Item = S>, S: AsRef<str>>( iter: I, ) -> Result<Self, CommandParseError>

Try to parse a sequence of arguments as a command

Errors

Should return an error for syntax or command-not-found errors, or for any errors while parsing arguments.

fn id(&self) -> Self::Id

Return an ID uniquely describing the base type of this command.

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.
