internal_exec: &InternalExecution,
input_invocation: Option<&VerbInvocation>,
trigger_type: TriggerType<'_>,
app_state: &mut AppState,
cc: &CmdContext<'_>
) -> Result<CmdResult, ProgramError>
execute the internal with the optional given invocation.
The invocation comes from the input and may be related to a different verb (the verb may have been triggered by a key shortcut)
fn selected_path(&self) -> Option<&Path>
fn selection(&self) -> Option<Selection<'_>>
fn refresh(&mut self, screen: Screen, con: &AppContext) -> Command
fn tree_options(&self) -> TreeOptions
sourcefn with_new_options(
&mut self,
screen: Screen,

) -> CmdResult
fn with_new_options(
&mut self,
screen: Screen,
change_options: &dyn Fn(&mut TreeOptions) -> &'static str,
in_new_panel: bool,
con: &AppContext
) -> CmdResult
Build a cmdResult in response to a command being a change of tree options. This may or not be a new state.
The provided change_options function returns a status message
explaining the change
fn display(
&mut self,
w: &mut W,
disc: &DisplayContext<'_>
) -> Result<(), ProgramError>
