Struct PushedTree 

pub struct PushedTree { /* private fields */ }

A checkout of the pushed commit, removed when it goes out of scope.

Implementations

impl PushedTree

pub fn create(settings: &Settings, repo: &Path, tip: &str) -> Option<PushedTree>

Materialise tip, or None when that is not possible — in which case the caller falls back to the working tree and says so. Takes the repository explicitly rather than relying on the working directory: set_current_dir is process-global, so a test that changed it would race every other test in the binary.

Checkout AND preparation, for the push-time caller: a snapshot that could not be prepared is no snapshot, said once, here.

pub fn checkout(repo: &Path, tip: &str) -> Option<PushedTree>

The checkout alone. The rehearsal registers itself between this and PushedTree::prepare, so an install that takes minutes is visible — to --status, to a push that would otherwise start over, and to a newer commit that must cancel it.

pub fn prepare(&self, settings: &Settings) -> Result<(), String>

Make the checkout runnable: carry, dependencies, then amont.snapshotPrepare. Err says why, in one line.

pub fn path(&self) -> &Path

Trait Implementations

impl Drop for PushedTree

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
