Struct easy_repl::command::Command[−][src]

pub struct Command<'a> {
    pub description: String,
    pub args_info: Vec<String>,
    pub handler: Box<Handler<'a>>,
}
Expand description

Single command that can be called in the REPL.

Though it is possible to construct it by manually, it is not advised. One should rather use the provided command! macro which will generate appropriate arguments validation and args_info based on passed specification.

Fields

description: String
Expand description

Command desctiption that will be displayed in the help message

args_info: Vec<String>
Expand description

Names and types of arguments to the command

handler: Box<Handler<'a>>
Expand description

Command handler which should validate arguments and perform command logic
