pub struct Pipeline {

    pub negation: bool,

Fields

commands: Vec<Rc<Command>>

Elements of the pipeline.

A valid pipeline must have at least one command.

The commands are contained in Rc to allow executing them asynchronously without cloning them.

negation: bool

True if the pipeline begins with a !.

Trait Implementations

impl Clone for Pipeline

fn clone(&self) -> Pipeline

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pipeline

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Pipeline

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for Pipeline

Converts a string to a pipeline.

type Err = Option<Error>

Optional error value

The error is None if the first token does not start a pipeline. A proper error is returned in Some(_) in case of a syntax error.

fn from_str(s: &str) -> Result<Pipeline, Option<Error>>

Parses a string s to return a value of this type.

impl PartialEq for Pipeline

fn eq(&self, other: &Pipeline) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Pipeline

impl StructuralEq for Pipeline
