Enum PipelineStage 

#[non_exhaustive]
pub enum PipelineStage {
    Command(Command),
    Compound(Box<Stmt>),
}

One stage of a pipeline. A stage is a command, or a compound statement (if, for, while, case) whose output feeds the pipe.

A compound stage buffers: its whole output is collected before the next stage sees a byte. See PipelineRunner::run_pipeline for why, and for the streaming work that would retire it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Command(Command)

Compound(Box<Stmt>)

Implementations

impl PipelineStage

pub fn as_command(&self) -> Option<&Command>

The command this stage runs, or None for a compound stage.

pub fn redirects(&self) -> &[Redirect]

Redirects attached to this stage. A compound stage carries none — the grammar does not accept a redirect after done/fi/esac.
