source ·
pub struct Flags(_);
Expand description

A wrapper type around i32 with convenience methods for checking if libc::O_* flags have been set.

Implementations§

source§

impl Flags

source

pub const fn new(value: i32) -> Self

Wraps the given i32 value.

source

pub const fn value(self) -> i32

Returns the inner i32 value.

source

pub const fn writeable(self) -> bool

Returns true if these flags allow the file to be written to.

source

pub const fn readable(self) -> bool

Returns true if these flags allow the file to be read from.

source

pub const fn read_only(self) -> bool

Returns true if the file was opened readonly.

source

pub const fn write_only(self) -> bool

Returns true if the file was opened writeonly

source

pub const fn directory(self) -> bool

Returns true if these flags are for a directory.

source

pub const fn process(self) -> bool

Returns true if these flags are for a process.

source

pub const fn server(self) -> bool

Returns true if these flags are for a server.

source

pub fn assert_readable(self) -> Result<(), Error>

Asserts that these flags allow a file to be read.

If the assertion fails then an io::Error with the errno [libc::EACCES] is returned.

source

pub fn assert_writeable(self) -> Result<(), Error>

Asserts that these flags allow a file to be written.

If the assertion fails then an io::Error with the errno [libc::EACCES] is returned.
