Enum PipelinePosition 

pub enum PipelinePosition {
    Only,
    First,
    Middle,
    Last,
}

Position of a command within a pipeline.

Used by external command execution to decide stdio inheritance:

• Only or Last in interactive mode → inherit terminal
• First or Middle → always capture

Variants

Only

Single command, no pipe.

First

First command in a pipeline (no stdin from pipe).

Middle

Middle of a pipeline (piped stdin, piped stdout).

Last

Last command in a pipeline (piped stdin, final output).

Trait Implementations

impl Clone for PipelinePosition

fn clone(&self) -> PipelinePosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PipelinePosition

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

Formats the value using the given formatter.

impl Default for PipelinePosition

fn default() -> PipelinePosition

Returns the “default value” for a type.

impl PartialEq for PipelinePosition

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

impl Copy for PipelinePosition

impl Eq for PipelinePosition

impl StructuralPartialEq for PipelinePosition
