    pub id: HttpRequestId,
}
Expand description

A struct representing an uncompleted http request.

Fields§

§id: HttpRequestId

Request ID

Implementations§

source§

impl PendingRequest

source

pub fn wait(self) -> HttpResult

Wait for the request to complete.

NOTE this waits for the request indefinitely.

source

pub fn try_wait( self, deadline: impl Into<Option<Timestamp>>, ) -> Result<HttpResult, PendingRequest>

Attempts to wait for the request to finish, but will return Err in case the deadline is reached.

source

pub fn wait_all(requests: Vec<PendingRequest>) -> Vec<HttpResult>

Wait for all provided requests.

source

pub fn try_wait_all( requests: Vec<PendingRequest>, deadline: impl Into<Option<Timestamp>>, ) -> Vec<Result<HttpResult, PendingRequest>>

Attempt to wait for all provided requests, but up to given deadline.

Requests that are complete will resolve to an Ok others will return a DeadlineReached error.
