Defines extension methods for the ServiceCollection struct.

Required Methods

fn add_options<T: Value + Default + 'static>(&mut self) -> Builder<'_, T>

Registers an options type that will have all of its associated services registered.

fn add_named_options<T: Value + Default + 'static>( &mut self, name: impl AsRef<str>, ) -> Builder<'_, T>

Registers an options type that will have all of its associated services registered.

Arguments

• name - The name associated with the options

Remarks

Names are matched using case-insensitive ASCII characters.

fn add_options_with<T, F>(&mut self, factory: F) -> Builder<'_, T>

where T: Value, F: Fn(&ServiceProvider) -> Ref<dyn Factory<T>> + 'static,

Registers an options type that will have all of its associated services registered.

Arguments

• factory - The function used to create the associated options factory

fn add_named_options_with<T, F>( &mut self, name: impl AsRef<str>, factory: F, ) -> Builder<'_, T>

where T: Value, F: Fn(&ServiceProvider) -> Ref<dyn Factory<T>> + 'static,

Registers an options type that will have all of its associated services registered.

Arguments

• name - The name associated with the options
• factory - The function used to create the associated options factory

Remarks

Names are matched using case-insensitive ASCII characters.

fn configure_options<T, F>(&mut self, setup: F) -> &mut Self

where T: Value + Default + 'static, F: Fn(&mut T) + 'static,

Registers an action used to initialize a particular type of configuration options.

Arguments

• setup - The setup action used to configure options.

fn configure_named_options<T, F>( &mut self, name: impl AsRef<str>, setup: F, ) -> &mut Self

where T: Value + Default + 'static, F: Fn(&mut T) + 'static,

Registers an action used to initialize a particular type of configuration options.

Arguments

• name - The name associated with the options
• setup - The setup action used to configure options

Remarks

Names are matched using case-insensitive ASCII characters.

fn post_configure_options<T, F>(&mut self, setup: F) -> &mut Self

where T: Value + Default + 'static, F: Fn(&mut T) + 'static,

Registers an action used to initialize a particular type of configuration options.

Arguments

• setup - The setup action used to configure options

fn post_configure_named_options<T, F>( &mut self, name: impl AsRef<str>, setup: F, ) -> &mut Self

where T: Value + Default + 'static, F: Fn(&mut T) + 'static,

Registers an action used to initialize a particular type of configuration options.

Arguments

• name - The name associated with the options
• setup - The setup action used to configure options

Remarks

Names are matched using case-insensitive ASCII characters.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
