Enum QueryProgramError 

pub enum QueryProgramError {
    ConnPoolQuery(AcquireThenQueryError),
    MissingLenBytes,
    InvalidLenBytes,
}

Any errors that might occur while querying for programs.

Variants

ConnPoolQuery(AcquireThenQueryError)

A DB query failure occurred.

MissingLenBytes

The queried program is missing the word that encodes its length.

InvalidLenBytes

Trait Implementations

impl Debug for QueryProgramError

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

Formats the value using the given formatter.

impl Display for QueryProgramError

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

Formats the value using the given formatter.

impl Error for QueryProgramError

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.
