pub fn new(bits: u16) -> MessageFlags

pub fn bits(self) -> u16

Trait Implementations

impl Clone for MessageFlags

fn clone(&self) -> MessageFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageFlags

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

Formats the value using the given formatter.

impl Default for MessageFlags

fn default() -> MessageFlags

Returns the “default value” for a type.

impl PartialEq for MessageFlags

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