Implementations

impl Dir

Create new Dir pointing to absolute file system path

pub fn path(&self) -> &Path

Path reference to file system directory

pub fn created(self) -> Self

Creates the directory using create and returns itself or stops the build with informative error message.

pub fn create(&self)

Creates the directory using create_result or stops the build with informative error message.

pub fn create_result(&self) -> Result<()>

Creates the directory and any missing parent directories on it’s path.

pub fn content<G: AsRef<str>>(&self, glob: G) -> DirContent<Unit>

All directory content (files, directories and links) matching given glob file name pattern

pub fn dirs<G: AsRef<str>>(&self, glob: G) -> DirContent<Dir>

All subdirectories and directory links matching given glob file name pattern

pub fn files<G: AsRef<str>>(&self, glob: G) -> DirContent<File>

All files and file links matching given glob file name pattern

pub fn dir<P: AsRef<Path>>(&self, path: P) -> Dir

Subdirectory at given relative path

Will stop the build with informative error message if path is not relative.

pub fn dir_result<P: AsRef<Path>>( &self, path: P, ) -> Result<Self, Box<dyn Error>>

Subdirectory at given relative path

pub fn file<P: AsRef<Path>>(&self, path: P) -> File

A file at given relative path

Will stop the build with informative error message if path is not relative.

pub fn file_result<P: AsRef<Path>>( &self, path: P, ) -> Result<File, Box<dyn Error>>

A file at given relative path

pub fn linked_from_inside(self, dir: &Dir) -> Self

Creating a link to this directory from another directory with this directory’s name returning self or stopping the build with informative error message.

If the directory already contains an entry with this name, linking fails.

pub fn link_from_inside(&self, dir: &Dir)

Creating a link to this directory from another directory with this directory’s name or stopping the build with informative error message.

If the directory already contains an entry with this name, linking fails.

pub fn link_from_inside_result(&self, dir: &Dir, force: bool) -> Result<()>

Creating a link to this directory from another directory with this directory’s name.

If the directory already contains a file or directory by this name, linking fails. To allow overwriting existing link with different target set force to true or linking to this directory will also fail.

pub fn linked_to(self, to: &Dir) -> Self

Create a symbolic link at this directory path to given target directory to creating any needed directories in the process returning self or stopping the build with informative error message.

If a file or directory by that name already exists, linking will fail.

pub fn link_to(&self, to: &Dir)

Create a symbolic link at this directory path to given target directory to creating any needed directories in the process or stopping the build with informative error message.

If a file or directory by that name already exists, linking will fail.

pub fn link_to_result(&self, to: &Dir, force: bool) -> Result<()>

Create a symbolic link at this directory path to given target directory to creating any needed directories in the process.

If a file or directory by that name already exists, linking will fail. To allow overwriting existing link to a different directory set force to true or linking to a different directory will also fail.

pub fn touched(self) -> Self

Touches the directory using touch and returns itself or stops the build with informative error message

pub fn touch(&self)

Touches the directory using touch and returns itself or stops the build with informative error message.

pub fn touch_result(&self) -> Result<()>

Touches the directory by updating it’s modification time or creating a new one if it does not exists yet including any needed directories.

impl Clone for Dir

fn clone(&self) -> Dir

Returns a copy of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl Display for Dir

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

Formats the value using the given formatter.

impl Hash for Dir

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Dir

fn cmp(&self, other: &Dir) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

Restrict a value to a certain interval.

impl PartialEq for Dir

fn eq(&self, other: &Dir) -> 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.

where R: Resource, S: AsResource<R>, F: FnOnce(),

Build the resource form a given src resource as a side product of given function by respecting resource timestamps meaning that function by will only be ran if the output needs to be build.

where R: Resource, S: AsRef<R>, F: FnOnce() -> Result<(), E>,
