Struct yash_syntax::syntax::Redir

pub struct Redir {
    pub fd: Option<Fd>,
    pub body: RedirBody,
}

Redirection.

Fields

fd: Option<Fd>

File descriptor that is modified by this redirection.

body: RedirBody

Nature of the resulting file descriptor.

Implementations

impl Redir

pub fn fd_or_default(&self) -> Fd

Computes the file descriptor that is modified by this redirection.

If self.fd is Some(_), the RawFd value is returned intact. Otherwise, the default file descriptor is selected depending on the type of self.body.

Trait Implementations

impl Clone for Redir

fn clone(&self) -> Redir

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Redir

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

Formats the value using the given formatter.

impl Display for Redir

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

Formats the value using the given formatter.

impl FromStr for Redir

Converts a string to a redirection.

This implementation does not support parsing a here-document.

type Err = Option<Error>

Optional error value

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

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

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

impl PartialEq<Redir> for Redir

fn eq(&self, other: &Redir) -> 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.
