Struct Open

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

The type of opening a file.

The type is stored in a 8-bit integer, with the following layout:

Create	Create exclusive	Truncate	Directory
0	1	2	3

Example

use file_system::Open_type;

let open = Open_type::new(true, true, false);

assert_eq!(open.get_create(), true);
assert_eq!(open.get_exclusive(), true);
assert_eq!(open.get_truncate(), false);

Implementations

impl Open

Trait Implementations

impl Clone for Open

fn clone(&self) -> Open

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Open

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

Formats the value using the given formatter.

impl Default for Open

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Open

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

impl Copy for Open

impl Eq for Open

impl StructuralPartialEq for Open
