Struct ExtCmdDocument 

pub struct ExtCmdDocument<D, F> {
    pub doc: D,
    pub handler: F,
}

A document-wrapper for handling commands.

Fields

doc: D

handler: F

Called whenever Document::run_command is called.

If handler returns CommandExecuted::Yes then the default handler on doc: D will not be called.

Implementations

impl<D: Document, F: Fn(&Editor, &Command, Option<usize>, Modifiers) -> CommandExecuted + 'static> ExtCmdDocument<D, F>

pub fn new(doc: D, handler: F) -> ExtCmdDocument<D, F>
