}Expand description
Extension trait for path-related filesystem operations.
Required Methods§
Sourcefn readable(&self) -> bool
fn readable(&self) -> bool
Returns true if the path exists and is readable by the current user.
Sourcefn writable(&self) -> bool
fn writable(&self) -> bool
Returns true if the path exists and is writable by the current user.
Sourcefn executable(&self) -> bool
fn executable(&self) -> bool
Returns true if the path exists and is executable by the current user.
On Windows, this returns true if either the path itself is a file with
a PATHEXT extension or appending some PATHEXT extension resolves
to an existing file. To recover the actual on-disk path in the
latter case, use resolve_executable which takes ownership
and avoids copies on platforms where no resolution is needed.
Sourcefn exists_and_is_block_device(&self) -> bool
fn exists_and_is_block_device(&self) -> bool
Returns true if the path exists and is a block device.
Sourcefn exists_and_is_char_device(&self) -> bool
fn exists_and_is_char_device(&self) -> bool
Returns true if the path exists and is a character device.
Sourcefn exists_and_is_fifo(&self) -> bool
fn exists_and_is_fifo(&self) -> bool
Returns true if the path exists and is a FIFO (named pipe).
Sourcefn exists_and_is_socket(&self) -> bool
fn exists_and_is_socket(&self) -> bool
Returns true if the path exists and is a socket.
Sourcefn exists_and_is_setgid(&self) -> bool
fn exists_and_is_setgid(&self) -> bool
Returns true if the path exists and has the setgid bit set.
Sourcefn exists_and_is_setuid(&self) -> bool
fn exists_and_is_setuid(&self) -> bool
Returns true if the path exists and has the setuid bit set.
Sourcefn exists_and_is_sticky_bit(&self) -> bool
fn exists_and_is_sticky_bit(&self) -> bool
Returns true if the path exists and has the sticky bit set.
Sourcefn get_device_and_inode(&self) -> Result<(u64, u64), Error>
fn get_device_and_inode(&self) -> Result<(u64, u64), Error>
Returns the device ID and inode number for the path.
§Errors
Returns crate::error::ErrorKind::IoError if the path’s metadata
cannot be read, for example because it does not exist. Platforms that
cannot report device and inode numbers return
crate::error::ErrorKind::NotSupportedOnThisPlatform or placeholder
values.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
