Enum ObserverBackpressure 

#[repr(i32)]
pub enum ObserverBackpressure {
    DropOldest = 0,
    Block = 1,
}

Backpressure for the bounded observer sink. Mirrors TeeBackpressure semantics: DropOldest never blocks the emitter, Block waits.

Variants

DropOldest = 0

Block = 1

Implementations

impl ObserverBackpressure

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ObserverBackpressure.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl ObserverBackpressure

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<Self>

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

Trait Implementations

impl Clone for ObserverBackpressure

fn clone(&self) -> ObserverBackpressure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ObserverBackpressure

impl Debug for ObserverBackpressure

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

Formats the value using the given formatter.

impl Default for ObserverBackpressure

fn default() -> ObserverBackpressure

Returns the “default value” for a type.

impl Eq for ObserverBackpressure

impl From<ObserverBackpressure> for i32

fn from(value: ObserverBackpressure) -> i32

Converts to this type from the input type.

impl Hash for ObserverBackpressure

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

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 ObserverBackpressure

fn cmp(&self, other: &ObserverBackpressure) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ObserverBackpressure

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
