Enum PubChemError 

pub enum PubChemError {
    NotFound {
        input: String,
    },
    NoUsableIdentifier,
    Http(String),
    Parse(String),
    RateLimitExceeded,
}

Errors produced by the PubChem API client.

Variants

NotFound

PubChem returned no compound matching the given input.

Fields

input: String

NoUsableIdentifier

The SubstanceIdentifier has no field usable for a PubChem lookup.

At least one of: CAS number, SMILES, InChIKey, InChI, or IUPAC name must be present.

Http(String)

HTTP-level error (network failure, server error, etc.).

Parse(String)

The API response could not be parsed.

RateLimitExceeded

PubChem server returned a rate-limit response (HTTP 429).

Trait Implementations

impl Debug for PubChemError

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

Formats the value using the given formatter.

impl Display for PubChemError

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

Formats the value using the given formatter.

impl Error for PubChemError

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.

impl From<PubChemError> for HsPredictError

fn from(source: PubChemError) -> Self

Converts to this type from the input type.
