Enum AccessMode

pub enum AccessMode {
    Read,
    Write,
    ReadWrite,
}

An enum that controls how a device will be opened

This mainly influences the flags passed to the underlying OS api, but is also used to avoid initializing read specific data structures for write-only devices.

In general Read means shared access and Write or ReadWrite means exclusive access

Variants

Write

ReadWrite

Implementations

impl AccessMode

pub fn readable(self) -> bool

pub fn writeable(self) -> bool

Trait Implementations

impl Clone for AccessMode

fn clone(&self) -> AccessMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccessMode

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

Formats the value using the given formatter.

impl Default for AccessMode

fn default() -> AccessMode

Returns the “default value” for a type.

impl PartialEq for AccessMode

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