impl FilePath

Exists

Checks if the file exists.

impl FilePath

Construction

pub unsafe fn new(path: StoragePath) -> Self

Creates a file path from the path.

Safety

The path must be a valid file path.

impl FilePath

Storage Path

pub fn path(&self) -> &StoragePath

Gets the storage path.

pub fn to_path(self) -> StoragePath

Converts the file path to a storage path.

impl FilePath

AsRef

pub fn as_str(&self) -> &str

Gets the path as a string.

impl FilePath

Clone

pub fn clone_with_extra_capacity(&self, extra_capacity: usize) -> Self

pub fn clone_append<S>(&self, string: S) -> StoragePath

where S: AsRef<str>,

Clones the path and appends the string.

The result is the same as path.clone().with_appended(s) but with a single allocation.
