Trait Implementations

impl Clone for Description

fn clone(&self) -> Description

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Description

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

Formats the value using the given formatter.

impl Display for Description

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

Formats the value using the given formatter.

impl From<v4l2_query_ext_ctrl> for Description

fn from(ctrl: v4l2_query_ext_ctrl) -> Self

Converts to this type from the input type.

impl PartialEq for Description

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