Enum RoutingPreference

#[repr(i32)]
pub enum RoutingPreference {
    Unspecified = 0,
    TrafficUnaware = 1,
    TrafficAware = 2,
    TrafficAwareOptimal = 3,
}

A set of values that specify factors to take into consideration when calculating the route.

Variants

Unspecified = 0

No routing preference specified. Default to TRAFFIC_AWARE.

TrafficUnaware = 1

Computes routes without taking live traffic conditions into consideration. Suitable when traffic conditions don’t matter or are not applicable. Using this value produces the lowest latency. Note: For RouteTravelMode DRIVE and TWO_WHEELER, the route and duration chosen are based on road network and average time-independent traffic conditions, not current road conditions. Consequently, routes may include roads that are temporarily closed. Results for a given request may vary over time due to changes in the road network, updated average traffic conditions, and the distributed nature of the service. Results may also vary between nearly-equivalent routes at any time or frequency.

TrafficAware = 2

Calculates routes taking traffic conditions into consideration. In contrast to TRAFFIC_AWARE_OPTIMAL, some optimizations are applied to significantly reduce latency.

TrafficAwareOptimal = 3

Calculates the routes taking traffic conditions into consideration, without applying most performance optimizations. Using this value produces the highest latency.

Implementations

impl RoutingPreference

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of RoutingPreference.

pub fn from_i32(value: i32) -> Option<RoutingPreference>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a RoutingPreference, or None if value is not a valid variant.

impl RoutingPreference

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<RoutingPreference>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for RoutingPreference

fn clone(&self) -> RoutingPreference

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RoutingPreference

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

Formats the value using the given formatter.

impl Default for RoutingPreference

fn default() -> RoutingPreference

Returns the “default value” for a type.

impl Hash for RoutingPreference

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RoutingPreference

fn cmp(&self, other: &RoutingPreference) -> 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,

Restrict a value to a certain interval.

impl PartialEq for RoutingPreference

fn eq(&self, other: &RoutingPreference) -> 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 PartialOrd for RoutingPreference

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<i32> for RoutingPreference

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<RoutingPreference, UnknownEnumValue>

Performs the conversion.
