Struct DbValueConvertError 

pub struct DbValueConvertError {
    pub source: DbValue,
    pub target_type: &'static str,
}

Error returned when a DbValue cannot be converted to the requested type.

Used by TryFrom<DbValue> impls for i32/i64/f64/String/bool/… and by QueryBuilder::min_internal / max_internal to surface type mismatches when reading aggregation results.

Fields

source: DbValue

The DbValue that could not be converted.

target_type: &'static str

The target Rust type name (e.g. "i32").

Trait Implementations

impl Clone for DbValueConvertError

fn clone(&self) -> DbValueConvertError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DbValueConvertError

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

Formats the value using the given formatter.

impl Display for DbValueConvertError

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

impl Error for DbValueConvertError

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.
