Enum alsa::ValueOr

pub enum ValueOr {
    Less = -1,
    Nearest = 0,
    Greater = 1,
}

Used to restrict hw parameters. In case the submitted value is unavailable, in which direction should one search for available values?

Variants

Less = -1

The value set is the submitted value, or less

Nearest = 0

The value set is the submitted value, or the nearest

Greater = 1

The value set is the submitted value, or greater

Trait Implementations

impl Clone for ValueOr

fn clone(&self) -> ValueOr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueOr

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

Formats the value using the given formatter.

impl Ord for ValueOr

fn cmp(&self, other: &ValueOr) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ValueOr

fn eq(&self, other: &ValueOr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ValueOr

fn partial_cmp(&self, other: &ValueOr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
