Struct ServiceCollection 

pub struct ServiceCollection { /* private fields */ }

Represents a service collection.

Implementations

impl ServiceCollection

pub fn new() -> Self

Creates and returns a new instance of the service collection.

pub fn is_empty(&self) -> bool

Returns true if the collection contains no elements.

pub fn len(&self) -> usize

Returns the number of elements in the collection.

pub fn clear(&mut self)

Removes all elements from the collection.

pub fn remove(&mut self, index: usize) -> ServiceDescriptor

Removes and returns the element at position index within the collection.

Argument

• index - The index of the element to remove

Panics

Panics if index is out of bounds.

pub fn add<T: Into<ServiceDescriptor>>(&mut self, descriptor: T) -> &mut Self

Adds a service using the specified service descriptor.

Arguments

• descriptor - The ServiceDescriptor to register

pub fn try_add<T: Into<ServiceDescriptor>>( &mut self, descriptor: T, ) -> &mut Self

Adds a service using the specified service descriptor if the service has not already been registered.

Arguments

• descriptor - The ServiceDescriptor to register

pub fn try_add_to_all<T: Into<ServiceDescriptor>>( &mut self, descriptor: T, ) -> &mut Self

Adds a service using the specified service descriptor if the service with same service and implementation type has not already been registered.

Arguments

• descriptor - The ServiceDescriptor to register

pub fn try_add_all( &mut self, descriptors: impl IntoIterator<Item = ServiceDescriptor>, ) -> &mut Self

Adds the specified service descriptors if each of the services are not already registered with the same service and implementation type.

Arguments

• descriptors - The ServiceDescriptor sequence to register

pub fn replace<T: Into<ServiceDescriptor>>( &mut self, descriptor: T, ) -> &mut Self

Removes the first service descriptor with the same service type and adds the replacement.

Arguments

• descriptor - The replacement ServiceDescriptor

pub fn try_replace<T: Into<ServiceDescriptor>>( &mut self, descriptor: T, ) -> &mut Self

Adds or replaces a service with the specified descriptor if the service has not already been registered.

Arguments

• descriptor - The replacement ServiceDescriptor

pub fn remove_all<T: Any + ?Sized>(&mut self) -> &mut Self

Removes all specified descriptors of the specified type.

pub fn build_provider(&self) -> Result<ServiceProvider, ValidationError>

Builds and returns a new ServiceProvider.

pub fn iter( &self, ) -> impl Iterator<Item = &ServiceDescriptor> + ExactSizeIterator + DoubleEndedIterator

Gets a read-only iterator for the collection
