Enum OpenAlexError 

pub enum OpenAlexError {
    Http(Error),
    Json(Error),
    Api {
        status: u16,
        message: String,
    },
}

Errors returned by OpenAlexClient methods.

Variants

• Http — network or connection failure (wraps reqwest::Error)
• Json — response body could not be deserialized (wraps serde_json::Error)
• Api — the OpenAlex API returned a non-success HTTP status code (e.g. 404 for unknown entity, 403 for forbidden, 500 for server error)

Example

use papers_openalex::{OpenAlexClient, GetParams, OpenAlexError};

let client = OpenAlexClient::new();
match client.get_work("nonexistent", &GetParams::default()).await {
    Ok(work) => println!("Found: {}", work.id),
    Err(OpenAlexError::Api { status, message }) => {
        eprintln!("API error {status}: {message}");
    }
    Err(e) => eprintln!("Other error: {e}"),
}

Variants

Http(Error)

Network or connection error from reqwest.

Json(Error)

Failed to deserialize the JSON response body.

Api

The API returned a non-success HTTP status code.

status is the HTTP status code (e.g. 404, 403, 500) and message contains the response body text.

Fields

status: u16

message: String

Trait Implementations

impl Debug for OpenAlexError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for OpenAlexError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for OpenAlexError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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.
