Enum PollError 

pub enum PollError {
    Fetch {
        url: String,
        message: String,
    },
    BadResponse {
        url: String,
        message: String,
    },
    TooManyPages {
        url: String,
        pages: u32,
    },
}

Why a listing could not complete. Every variant means the caller has no records at all from this attempt – see this module’s doc comment on why a failed listing must never apply a partial result.

Variants

Fetch

A network or HTTP-level failure fetching some page of the listing.

Fields

url: String

The URL that failed.

message: String

What went wrong.

BadResponse

A page’s body was not the shape listRecords promises.

Fields

url: String

The URL whose response did not parse.

message: String

What went wrong.

TooManyPages

A listing kept answering with another full page, past the cap on how many one listing follows.

Fields

url: String

The endpoint that would not stop.

pages: u32

The cap it ran into.

Trait Implementations

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
