Struct Cfg 

pub struct Cfg<T>(/* private fields */)
where
    T: Configuration;

A typed handle to a value in a SharedCfg.

Implementations

impl<T> Cfg<T>

where T: Configuration,

pub fn id(&self) -> usize

Returns the unique identifier of the shared configuration.

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

Returns the configuration tag.

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

Returns the configured service name.

pub fn shared(&self) -> SharedCfg

Returns a handle to the complete shared configuration.

pub fn get_shared<U>(&self) -> Cfg<U>

where U: Configuration,

Returns another typed value from the same shared configuration.

pub unsafe fn replace(&self, cfg: Cfg<T>)

Replaces the inner value.

Safety

The caller must guarantee that no references to the inner T value exist at the time this function is called.

Trait Implementations

impl<T> Clone for Cfg<T>

where T: Configuration,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Cfg<T>

where T: Debug + Configuration,

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

Formats the value using the given formatter.

impl<T> Default for Cfg<T>

where T: Configuration,

fn default() -> Cfg<T>

Returns the “default value” for a type.

impl<T> Deref for Cfg<T>

where T: Configuration,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T> Drop for Cfg<T>

where T: Configuration,

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
