Trait Build

pub trait Build<Name, Error>: Node + Sized
where
    Self::DirectoryContent: IntoIterator<Item = (Name, Self)>,
{
    type BorrowedPath: ToOwned<Owned = Self::OwnedPath> + ?Sized;
    type OwnedPath: AsRef<Self::BorrowedPath>;

    // Required methods
    fn join(prefix: &Self::BorrowedPath, name: &Name) -> Self::OwnedPath;
    fn write_file(
        path: &Self::BorrowedPath,
        content: &Self::FileContent,
    ) -> Result<(), Error>;
    fn create_dir(path: &Self::BorrowedPath) -> Result<(), Error>;

    // Provided method
    fn build<Path>(
        self,
        path: Path,
    ) -> Result<(), BuildError<Self::OwnedPath, Error>>
       where Path: AsRef<Self::BorrowedPath> { ... }
}

Applying FileSystemTree to the filesystem.

Generic parameters:

• Name: Identification of a child item.
• Error: Error type used by the other functions.

Required Associated Types

type BorrowedPath: ToOwned<Owned = Self::OwnedPath> + ?Sized

Build target.

type OwnedPath: AsRef<Self::BorrowedPath>

Locations of the items in the filesystem.

Required Methods

fn join(prefix: &Self::BorrowedPath, name: &Name) -> Self::OwnedPath

Add prefix to the root of the tree.

fn write_file( path: &Self::BorrowedPath, content: &Self::FileContent, ) -> Result<(), Error>

Write content to a file.

fn create_dir(path: &Self::BorrowedPath) -> Result<(), Error>

Create a directory at root.

Provided Methods

fn build<Path>( self, path: Path, ) -> Result<(), BuildError<Self::OwnedPath, Error>>

where Path: AsRef<Self::BorrowedPath>,

Build the tree into the filesystem.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
