Enum ConvertError 

#[non_exhaustive]
pub enum ConvertError {
    KindMismatch {
        want: Kind,
        got: Kind,
    },
    NotNull,
    Convert(Box<dyn Error + Send + Sync>),
}

Represent failures in converting a Spanner Value to a Rust type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

KindMismatch

The value kind is not as expected.

Fields

want: Kind

The expected Spanner value kind.

got: Kind

The actual Spanner value kind.

NotNull

The value is null, but the target type does not support nulls.

Convert(Box<dyn Error + Send + Sync>)

There was a problem during conversion.

Trait Implementations

impl Debug for ConvertError

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

Formats the value using the given formatter.

impl Display for ConvertError

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

Formats the value using the given formatter.

impl Error for ConvertError

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.
