Trait Implementations

impl Clone for Echo

fn clone(&self) -> Echo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Command for Echo

fn name(&self) -> &str

fn description(&self) -> &str

Short preferably single sentence description for the command.

fn signature(&self) -> Signature

fn extra_description(&self) -> &str

Longer documentation description, if necessary.

fn run( &self, engine_state: &EngineState, stack: &mut Stack, call: &Call<'_>, _input: PipelineData, ) -> Result<PipelineData, ShellError>

fn examples(&self) -> Vec<Example<'_>>

fn run_const( &self, working_set: &StateWorkingSet<'_>, call: &Call<'_>, input: PipelineData, ) -> Result<PipelineData, ShellError>

Used by the parser to run command at parse time

fn search_terms(&self) -> Vec<&str>

fn is_const(&self) -> bool

fn is_sub(&self) -> bool

fn block_id(&self) -> Option<Id<Block>>

fn as_alias(&self) -> Option<&Alias>

fn plugin_identity(&self) -> Option<&PluginIdentity>

The identity of the plugin, if this is a plugin command

fn command_type(&self) -> CommandType

fn is_builtin(&self) -> bool

fn is_custom(&self) -> bool

fn is_keyword(&self) -> bool

fn is_known_external(&self) -> bool

fn is_alias(&self) -> bool

fn is_plugin(&self) -> bool

fn pipe_redirection(&self) -> (Option<OutDest>, Option<OutDest>)

fn requires_ast_for_arguments(&self) -> bool

Return true if the AST nodes for the arguments are required for IR evaluation. This is currently inefficient so is not generally done.
