Enum Sample 

pub enum Sample<D, K> {
    Value(D),
    Dispose(K),
}

A data sample received from a WITH_KEY Topic without the associated metadata.

Replaces the use of valid_data flag in SampleInfo of DataSample from the DDS spec.

Implements the methods value, map_value, map_dispose, and as_ref. The unwrap method is deprecated — use value() or match on Sample::Value / Sample::Dispose instead.

Variants

Value(D)

Dispose(K)

Implementations

impl<D, K> Sample<D, K>

pub fn value(self) -> Option<D>

pub fn map_value<D2, F: FnOnce(D) -> D2>(self, op: F) -> Sample<D2, K>

pub fn map_dispose<K2, F: FnOnce(K) -> K2>(self, op: F) -> Sample<D, K2>

pub fn unwrap(self) -> D

👎Deprecated:

panics on Sample::Dispose; use value() or match on Sample::Value/Dispose

Returns the data sample, panicking if this is a dispose notification.

Panics

Panics if called on Sample::Dispose. Use Self::value or match on Sample::Value / Sample::Dispose.

pub const fn as_ref(&self) -> Sample<&D, &K>

Trait Implementations
