Struct RuntimeDirRoots 

pub struct RuntimeDirRoots {
    pub runtime: WorkdirRoot,
    pub sealed_etc: WorkdirRoot,
    pub harness: WorkdirRoot,
    pub records: Option<WorkdirRoot>,
    pub temp: Option<WorkdirRoot>,
    pub home: Option<WorkdirRoot>,
}

The three held directories beneath one session’s <session-id>/, and the session’s records directory beside them, each sharing the session’s refusal latch: every directory outside the workdir a command is told of or a sealed root is composed from. Cheap to clone.

Fields

runtime: WorkdirRoot

runtime/, which $MURMUR_RUNTIME_DIR names.

sealed_etc: WorkdirRoot

sealed-etc/.

harness: WorkdirRoot

harness/.

records: Option<WorkdirRoot>

The session’s records directory, which $MURMUR_RECORDS_DIR names, given the same read-only rule and bind as runtime/. None for roots held outside a session, where no records directory exists.

temp: Option<WorkdirRoot>

The session’s temporary folder, tmp/ in its records directory: $TMPDIR in every command, and /tmp wherever the session maps it (crate::temp_dir). None for roots held outside a session, whose commands are told of no temporary folder.

home: Option<WorkdirRoot>

The session’s home folder, home/ in its records directory: $HOME in every command, granted exactly as Self::temp is. None for roots held outside a session, where no command runs.

Implementations

impl RuntimeDirRoots

pub fn new( runtime: WorkdirRoot, sealed_etc: WorkdirRoot, harness: WorkdirRoot, ) -> Self

The three roots of a session’s runtime directory, for a caller that holds them itself — a test, or a plan run outside a session. No records directory.

pub fn with_records(self, records: WorkdirRoot) -> Self

These roots with records as the session’s records directory.

pub fn with_temp(self, temp: WorkdirRoot) -> Self

These roots with temp as the session’s temporary folder.

pub fn with_home(self, home: WorkdirRoot) -> Self

These roots with home as the session’s home folder.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for RuntimeDirRoots

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