Enum RedirectOrEnvVar

pub enum RedirectOrEnvVar<R, V, W> {
    Redirect(R),
    EnvVar(V, Option<W>),
}

Represents a parsed redirect or a defined environment variable at the start of a command.

Because the order in which redirects are defined may be significant for execution, the parser will preserve the order in which they were parsed. Thus we need a wrapper like this to disambiguate what was encountered in the source program.

Variants

Redirect(R)

A parsed redirect before a command was encountered.

EnvVar(V, Option<W>)

A parsed environment variable, e.g. foo=[bar].

Trait Implementations

impl<R: Clone, V: Clone, W: Clone> Clone for RedirectOrEnvVar<R, V, W>

fn clone(&self) -> RedirectOrEnvVar<R, V, W>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<R: Debug, V: Debug, W: Debug> Debug for RedirectOrEnvVar<R, V, W>

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

Formats the value using the given formatter.

impl<R: PartialEq, V: PartialEq, W: PartialEq> PartialEq for RedirectOrEnvVar<R, V, W>

fn eq(&self, other: &RedirectOrEnvVar<R, V, W>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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