Struct ic_utils::call::MappedAsyncCaller

pub struct MappedAsyncCaller<Out: for<'de> ArgumentDecoder<'de> + Send, Out2: for<'de> ArgumentDecoder<'de> + Send, Inner: AsyncCall<Out> + Send, Map: Send + Fn(Out) -> Out2> { /* fields omitted */ }

A structure that applies a transform function to the result of a call. Because of constraints on the type system in Rust, both the input and output to the function must be deserializable.

Implementations

impl<Out, Out2, Inner, Map> MappedAsyncCaller<Out, Out2, Inner, Map> where
    Out: for<'de> ArgumentDecoder<'de> + Send,
    Out2: for<'de> ArgumentDecoder<'de> + Send,
    Inner: AsyncCall<Out> + Send,
    Map: Send + Fn(Out) -> Out2, 

pub fn new(inner: Inner, map: Map) -> Self

pub async fn call(self) -> Result<RequestId, AgentError>

pub async fn call_and_wait<W>(self, waiter: W) -> Result<Out2, AgentError> where
    W: Waiter, 

pub fn and_then<Out3, R2, AndThen2>(
    self,
    and_then: AndThen2
) -> AndThenAsyncCaller<Out2, Out3, Self, R2, AndThen2> where
    Out3: for<'de> ArgumentDecoder<'de> + Send,
    R2: Future<Output = Result<Out3, AgentError>> + Send,
    AndThen2: Send + Fn(Out2) -> R2, 

pub fn map<Out3, Map2>(
    self,
    map: Map2
) -> MappedAsyncCaller<Out2, Out3, Self, Map2> where
    Out3: for<'de> ArgumentDecoder<'de> + Send,
    Map2: Send + Fn(Out2) -> Out3, 

Trait Implementations

impl<Out, Out2, Inner, Map> AsyncCall<Out2> for MappedAsyncCaller<Out, Out2, Inner, Map> where
    Out: for<'de> ArgumentDecoder<'de> + Send,
    Out2: for<'de> ArgumentDecoder<'de> + Send,
    Inner: AsyncCall<Out> + Send,
    Map: Send + Fn(Out) -> Out2, 

fn call<'async_trait>(
    self
) -> Pin<Box<dyn Future<Output = Result<RequestId, AgentError>> + Send + 'async_trait>> where
    Self: 'async_trait, 

Execute the call, but returns the RequestId. Waiting on the request Id must be managed by the caller using the Agent directly.

fn call_and_wait<'async_trait, W>(
    self,
    waiter: W
) -> Pin<Box<dyn Future<Output = Result<Out2, AgentError>> + Send + 'async_trait>> where
    W: Waiter,
    W: 'async_trait,
    Self: 'async_trait, 

Execute the call, and wait for an answer using a Waiter strategy. The return type is encoded in the trait.

fn and_then<Out2, R, AndThen>(
    self,
    and_then: AndThen
) -> AndThenAsyncCaller<Out, Out2, Self, R, AndThen> where
    Self: Sized + Send,
    Out2: for<'de> ArgumentDecoder<'de> + Send,
    R: Future<Output = Result<Out2, AgentError>> + Send,
    AndThen: Send + Fn(Out) -> R, 

Apply a transformation function after the call has been successful. The transformation is applied with the result.

fn map<Out2, Map>(self, map: Map) -> MappedAsyncCaller<Out, Out2, Self, Map> where
    Self: Sized + Send,
    Out2: for<'de> ArgumentDecoder<'de> + Send,
    Map: Send + Fn(Out) -> Out2,
