Enum glean::traits::NoExtraKeys

pub enum NoExtraKeys {}

Default of no extra keys for events.

An enum with no values for convenient use as the default set of extra keys that an EventMetric can accept.

Note: There exist no values for this enum, it can never exist. It its equivalent to the never / ! type.

Trait Implementations

impl Clone for NoExtraKeys

fn clone(&self) -> NoExtraKeys

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NoExtraKeys

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

Formats the value using the given formatter.

impl ExtraKeys for NoExtraKeys

const ALLOWED_KEYS: &'static [&'static str] = _

List of allowed extra keys as strings.

fn into_ffi_extra(self) -> HashMap<String, String>

Convert the event extras into 2 lists:

impl Hash for NoExtraKeys

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 PartialEq for NoExtraKeys

fn eq(&self, other: &NoExtraKeys) -> 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 TryFrom<&str> for NoExtraKeys

type Error = EventRecordingError

The type returned in the event of a conversion error.

fn try_from( _value: &str ) -> Result<NoExtraKeys, <NoExtraKeys as TryFrom<&str>>::Error>

Performs the conversion.

impl TryFrom<i32> for NoExtraKeys

type Error = EventRecordingError

The type returned in the event of a conversion error.

fn try_from( _value: i32 ) -> Result<NoExtraKeys, <NoExtraKeys as TryFrom<i32>>::Error>

Performs the conversion.
