Enum Reading 

pub enum Reading<T> {
    Read(T),
    Withheld(Withheld),
}

A reading, or why the log can’t support it.

Serialized, the status goes in beside the reading’s own fields ("status": "read"), so T must serialize as a map, as the reading structs here do.

Variants

Read(T)

The reading, with where it came from.

Withheld(Withheld)

The log can’t support the reading.

Implementations

impl<T> Reading<T>

pub fn value(&self) -> Option<&T>

The reading, if it wasn’t withheld.

Trait Implementations

impl<T: Clone> Clone for Reading<T>

fn clone(&self) -> Reading<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Reading<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Reading<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq> PartialEq for Reading<T>

fn eq(&self, other: &Reading<T>) -> 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<T> Serialize for Reading<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
