Struct aws_smithy_runtime::client::config_override::Resolver

pub struct Resolver<'a> { /* private fields */ }

Available on crate feature client only.

Utility to simplify config building and config overrides.

The resolver allows the same initialization logic to be reused for both initial config and override config.

This resolver can be initialized to one of two modes:

1. Initial mode: The resolver is being used in a service Config builder’s build() method, and thus, there is no config override at this point.
2. Override mode: The resolver is being used by the ConfigOverrideRuntimePlugin’s constructor and needs to incorporate both the original config and the given config override for this operation.

In all the methods on Resolver, the term “latest” refers to the initial config when in Initial mode, and to config override when in Override mode.

Implementations

impl<'a> Resolver<'a>

pub fn initial( config: &'a mut CloneableLayer, components: &'a mut RuntimeComponentsBuilder, ) -> Self

Construct a new Resolver in initial mode.

pub fn overrid( initial_config: FrozenLayer, initial_components: &'a RuntimeComponentsBuilder, config: &'a mut CloneableLayer, components: &'a mut RuntimeComponentsBuilder, ) -> Self

Construct a new Resolver in override mode.

pub fn is_initial(&self) -> bool

Returns true if in initial mode.

pub fn config_mut(&mut self) -> &mut CloneableLayer

Returns a mutable reference to the latest config.

pub fn runtime_components_mut(&mut self) -> &mut RuntimeComponentsBuilder

Returns a mutable reference to the latest runtime components.

pub fn is_latest_set<T>(&self) -> bool

where T: Storable<Storer = StoreReplace<T>>,

Returns true if the latest config has T set.

The “latest” is initial for Resolver::Initial, and override for Resolver::Override.

pub fn is_set<T>(&self) -> bool

where T: Storable<Storer = StoreReplace<T>>,

Returns true if T is set anywhere.

pub fn resolve_config<T>(&self) -> <T::Storer as Store>::ReturnedType<'_>

where T: Storable<Storer = StoreReplace<T>>,

Resolves the value T with fallback

pub fn sleep_impl(&self) -> Option<SharedAsyncSleep>

The async sleep implementation.

pub fn latest_sleep_impl(&self) -> Option<SharedAsyncSleep>

The async sleep implementation.
