Variants

SqliteError(Error)

A SQLite error from the PDG database.

Io(Error)

An I/O error occurred while reading, writing, or caching the PDG database.

CacheDirectoryUnavailable

No OS-specific cache directory could be found.

OfflineDatabaseMissing(PathBuf)

The PDG database is not cached and network access is disabled.

Download(String)

Downloading the PDG database failed.

DatabaseSizeMismatch

A cached or downloaded PDG database has the wrong byte length.

Fields

path: PathBuf

Path to the database file that was checked.

expected: u64

Expected byte length.

actual: u64

Actual byte length.

DatabaseChecksumMismatch

A cached or downloaded PDG database has the wrong SHA-256 digest.

Fields

path: PathBuf

Path to the database file that was checked.

expected: &'static str

Expected SHA-256 digest.

actual: String

Actual SHA-256 digest.

ParseValueType(String)

A value type code was not recognized.

ParseLimitType(String)

A limit type code was not recognized.

ParseDataType(String)

A data type code was not recognized.

QuantumNumberConversion(QuantumNumberConversionError)

A quantum number could not be converted into the requested numeric representation.

Custom(String)

An application-specific error message.

Trait Implementations

impl Debug for PdgError

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

Formats the value using the given formatter.

impl Display for PdgError

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

Formats the value using the given formatter.

impl Error for PdgError

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<Error> for PdgError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for PdgError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<QuantumNumberConversionError> for PdgError

fn from(source: QuantumNumberConversionError) -> Self

Converts to this type from the input type.
