pub struct JobManager {
    pub jobs: Vec<Job>,
}

Manages the jobs that are currently managed by the shell.

Fields

jobs: Vec<Job>

The jobs that are currently managed by the shell.

Implementations

impl JobManager

pub fn new() -> Self

Returns a new job manager.

pub fn add_as_current(&mut self, job: Job) -> &Job

Adds a job to the job manager and marks it as the current job; returns an immutable reference to the job.

Arguments

• job - The job to add.

Does not panic in practice: the job list is non-empty because the job was pushed just before the final lookup.

pub fn current_job(&self) -> Option<&Job>

Returns the current job, if there is one.

pub fn current_job_mut(&mut self) -> Option<&mut Job>

Returns a mutable reference to the current job, if there is one.

pub fn prev_job(&self) -> Option<&Job>

Returns the previous job, if there is one.

pub fn prev_job_mut(&mut self) -> Option<&mut Job>

Returns a mutable reference to the previous job, if there is one.

pub fn resolve_job_spec(&mut self, job_spec: &str) -> Option<&mut Job>

Tries to resolve the given job specification to a job.

Arguments

• job_spec - The job specification to resolve.

pub async fn wait_all(&mut self) -> Result<Vec<Job>, Error>

Waits for all managed jobs to complete.

Errors

Returns the first error from Job::wait; jobs after it are not waited on.

pub fn poll( &mut self, ) -> Result<Vec<(Job, Result<ExecutionResult, Error>)>, Error>

Polls all managed jobs for completion.

Errors

Returns the first error from Job::poll_done.
