Struct yash_syntax::syntax::SimpleCommand

pub struct SimpleCommand<H = HereDoc> {
    pub assigns: Vec<Assign>,
    pub words: Vec<Word>,
    pub redirs: Rc<Vec<Redir<H>>>,
}

Command that involves assignments, redirections, and word expansions.

In the shell language syntax, a valid simple command must contain at least one of assignments, redirections, and words. The parser must not produce a completely empty simple command.

Fields

assigns: Vec<Assign>

words: Vec<Word>

redirs: Rc<Vec<Redir<H>>>

Implementations

impl<H> SimpleCommand<H>

pub fn is_empty(&self) -> bool

Returns true if the simple command does not contain any assignments, words, or redirections.

pub fn is_one_word(&self) -> bool

Returns true if the simple command contains only one word.

Trait Implementations

impl<H: Clone> Clone for SimpleCommand<H>

fn clone(&self) -> SimpleCommand<H>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H: Debug> Debug for SimpleCommand<H>

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

Formats the value using the given formatter.

impl<H: Display> Display for SimpleCommand<H>

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

Formats the value using the given formatter.

impl Fill<HereDoc> for SimpleCommand<MissingHereDoc>

type Full = SimpleCommand

Final AST created by filling self.

fn fill(self, i: &mut dyn Iterator<Item = HereDoc>) -> Result<SimpleCommand>

Takes some items from the iterator and fills the missing parts of self to create the complete AST.

impl FromStr for SimpleCommand<MissingHereDoc>

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

Converts a string to a simple command.

Returns Err(None) if the first token does not start a simple command.

type Err = Option<Error>

The associated error which can be returned from parsing.

impl FromStr for SimpleCommand

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

Converts a string to a simple command.

Returns Err(None) if the first token does not start a simple command.

This function does not support parsing a command that contains a here-document.

type Err = Option<Error>

The associated error which can be returned from parsing.

impl<H: PartialEq> PartialEq<SimpleCommand<H>> for SimpleCommand<H>

fn eq(&self, other: &SimpleCommand<H>) -> bool

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

fn ne(&self, other: &SimpleCommand<H>) -> bool

This method tests for !=.
