Struct Diff

pub struct Diff<F>(/* private fields */);

A Visitor implementation which checks for changes which would be made by a deployment. For each change an Event is emitted which can be processed by [Diff.0].

Implementations

impl<F> Diff<F>

where F: Fn(Event<'_>),

pub const fn new(f: F) -> Self

Creates a new instance of the visitor.

pub fn diff(self, source: &PunktfSource, profile: &mut LayeredProfile)

Runs the visitor to completion for a given profile.

Trait Implementations

impl<F: Clone> Clone for Diff<F>

fn clone(&self) -> Diff<F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for Diff<F>

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

Formats the value using the given formatter.

impl<F> TemplateVisitor for Diff<F>

where F: Fn(Event<'_>),

fn accept_template<'a>( &mut self, _: &PunktfSource, profile: &LayeredProfile, file: &File<'a>, resolve_content: impl FnOnce(&str) -> Result<String>, ) -> Result

Accepts a file template item and checks if it differs in any way to the counter part on the filesystem (deployed item).

If so, a change Event::NewFile/Event::Diff is emitted.

impl<F> Visitor for Diff<F>

where F: Fn(Event<'_>),

fn accept_file<'a>( &mut self, _: &PunktfSource, profile: &LayeredProfile, file: &File<'a>, ) -> Result

Accepts a file item and checks if it differs in any way to the counter part on the filesystem (deployed item).

If so, a change Event::NewFile/Event::Diff is emitted.

fn accept_directory<'a>( &mut self, _: &PunktfSource, _: &LayeredProfile, directory: &Directory<'a>, ) -> Result

Accepts a directory item and simply checks if it already exists on the filesystem.

If no, a change Event::NewDirectory is emitted.

fn accept_link( &mut self, _: &PunktfSource, _: &LayeredProfile, link: &Symlink, ) -> Result

Accepts a rejected item and does nothing besides logging an info message.

NOTE

Links are currently not supported for diffing.

fn accept_rejected<'a>( &mut self, _: &PunktfSource, _: &LayeredProfile, rejected: &Rejected<'a>, ) -> Result

Accepts a rejected item and does nothing besides logging an info message.

fn accept_errored<'a>( &mut self, _: &PunktfSource, _: &LayeredProfile, errored: &Errored<'a>, ) -> Result

Accepts a rejected item and does nothing besides logging an error message.
