Struct commands::parser::CommandNode [−] [src]

pub struct CommandNode {
    pub node: TreeNode,
    pub handler: Option<fn(node: Node)>,
    pub parameters: Vec<Rc<Node>>,
    pub wrapped_root: Option<Rc<Node>>,
}

A node representing a command. Constructed via Command and CommandTree.

If wrapped_root is set then this node wraps another command. This is used for the help command so that it can complete normal commands. The successors will be those of the wrapped node.

Fields

`node`	`TreeNode` data.
`handler`	The handler which is executed once this node has been accepted.
`parameters`	Parameter nodes for this command
`wrapped_root`	If present, the command wrapped by this node.

Methods

`impl CommandNode`

`fn new(name: &str, help_text: Option<&str>, hidden: bool, priority: i32, successors: Vec<Rc<Node>>, handler: Option<fn(node: Node)>, parameters: Vec<Rc<Node>>) -> Self`

Construct a new CommandNode.
