pub struct OpenOptions(/* private fields */);

Describes the options for opening a file or directory.

Implementations

impl OpenOptions

pub const WRITE: Self

Open the file for writing.

pub const READ: Self

Open the file for reading.

pub const CREATE_FILE: Self

Create the file if it does not exist.

pub const CREATE_DIRECTORY: Self

Create the directory if it does not exist. (doesn’t create parent directories)

pub const WRITE_TRUNCATE: Self

Truncate the file to zero length if it already exists.

pub const fn from_bits(bits: u8) -> Self

pub const fn contains(self, other: Self) -> bool

pub const fn is_write(&self) -> bool

pub const fn is_write_truncate(&self) -> bool

pub const fn is_read(&self) -> bool

pub const fn create_file(&self) -> bool

pub const fn create_dir(&self) -> bool

Trait Implementations

impl BitOr for OpenOptions

type Output = OpenOptions

The resulting type after applying the | operator.

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

Performs the | operation.

impl Clone for OpenOptions

fn clone(&self) -> OpenOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenOptions

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

Formats the value using the given formatter.

impl PartialEq for OpenOptions

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