Struct git_nomad::git_binary::GitBinary

pub struct GitBinary<'name> {
    pub verbosity: Option<Verbosity>,
    name: Cow<'name, str>,
    git_dir: String,
}

Implements repository manipulations by delegating to some ambient git binary that exists somewhere on the system.

Fields

verbosity: Option<Verbosity>

Used to actually execute commands while reporting progress to the user.

name: Cow<'name, str>

The name of the git binary to use. Implemented on top of Command::new, so non-absolute paths are looked up against $PATH.

git_dir: String

The absolute path to the .git directory of the repository.

Implementations

impl<'name> GitBinary<'name>

pub fn new( renderer: &mut impl Renderer, verbosity: Option<Verbosity>, name: Cow<'name, str>, cwd: &Path, ) -> Result<Self>

Create a new GitBinary by finding the .git dir relative to cwd, which implements the usual git rules of searching ancestor directories.

impl GitBinary<'_>

pub fn command(&self) -> Command

Invoke a git sub-command with an explicit --git-dir to make it independent of the working directory it is invoked from.

pub fn get_config( &self, renderer: &mut impl Renderer, key: &str, ) -> Result<Option<String>>

Wraps git config to read a single namespaced value.

fn get_config_with_env( &self, renderer: &mut impl Renderer, key: &str, vars: impl IntoIterator<Item = (impl AsRef<OsStr>, impl AsRef<OsStr>)>, ) -> Result<Option<String>>

fn fetch_refspecs<Description, RefSpec>( &self, renderer: &mut impl Renderer, description: Description, remote: &Remote<'_>, refspecs: &[RefSpec], ) -> Result<()>

where Description: AsRef<str>, RefSpec: AsRef<OsStr>,

Wraps git fetch to fetch refs from a given remote into the local repository.

Panics

If refspecs is empty, which means git will use the user configured default behaviour which is definitely not what we want.

fn push_refspecs<Description, RefSpec>( &self, renderer: &mut impl Renderer, description: Description, remote: &Remote<'_>, refspecs: &[RefSpec], ) -> Result<()>

where Description: AsRef<str>, RefSpec: AsRef<OsStr>,

Wraps git push to push refs from the local repository into the given remote.

Panics

If refspecs is empty, which means git will use the user configured default behaviour which is definitely not what we want.

pub fn list_refs<Description>( &self, renderer: &mut impl Renderer, description: Description, ) -> Result<Vec<GitRef>>

where Description: AsRef<str>,

List all the non-HEAD refs in the repository as GitRefs.

fn list_remote_refs<Description, RefSpec>( &self, renderer: &mut impl Renderer, description: Description, remote: &Remote<'_>, refspecs: &[RefSpec], ) -> Result<Vec<GitRef>>

where Description: AsRef<str>, RefSpec: AsRef<OsStr>,

Wraps git ls-remote to query a remote for all refs that match the given refspecs.

Panics

If refspecs is empty, which means git will list all refs, which is never what we want.

fn delete_ref<Description>( &self, renderer: &mut impl Renderer, description: Description, git_ref: &GitRef, ) -> Result<()>

where Description: AsRef<str>,

Delete a ref from the repository.

Note that deleting refs on a remote is done via GitBinary::push_refspecs.

pub fn current_branch( &self, renderer: &mut impl Renderer, ) -> Result<Branch<'static>>

Get the current branch, which may fail if the work tree is in a detached HEAD state.

pub fn is_output_allowed(&self) -> bool

Should higher level commands be producing output, or has the user requested quiet mode?

pub fn snapshot<'a>( &self, renderer: &mut impl Renderer, user: &'a User<'_>, ) -> Result<Snapshot<'a, GitRef>>

Build a point in time snapshot for all refs that nomad cares about from the state in the local git clone.

pub fn fetch_nomad_refs( &self, renderer: &mut impl Renderer, user: &User<'_>, remote: &Remote<'_>, ) -> Result<()>

Fetch all nomad managed refs from a given remote.

pub fn list_nomad_refs( &self, renderer: &mut impl Renderer, user: &User<'_>, remote: &Remote<'_>, ) -> Result<impl Iterator<Item = NomadRef<'_, GitRef>>>

List all nomad managed refs from a given remote.

Separated from Self::fetch_nomad_refs because not all callers want to pay the overhead of actually listing the fetched refs.

pub fn push_nomad_refs( &self, renderer: &mut impl Renderer, user: &User<'_>, host: &Host<'_>, remote: &Remote<'_>, ) -> Result<()>

Push local branches to nomad managed refs in the remote.

pub fn prune_nomad_refs<'a>( &self, renderer: &mut impl Renderer, remote: &Remote<'_>, prune: impl Iterator<Item = PruneFrom<'a, GitRef>>, ) -> Result<()>

Delete the given nomad managed refs.

Trait Implementations

impl<'name> PartialEq for GitBinary<'name>

fn eq(&self, other: &GitBinary<'name>) -> 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.
