Enum PostgresProjectionSourceError 

#[non_exhaustive]
pub enum PostgresProjectionSourceError {
    ConnectionFailed(Error),
    MigrationFailed(Error),
    ReadFailed(Error),
    InvalidPersistedValue {
        field: &'static str,
        detail: String,
    },
}

Errors returned by PostgresProjectionSource.

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.

ConnectionFailed(Error)

Connecting the source’s PostgreSQL pool failed.

MigrationFailed(Error)

Applying the projection source’s component-scoped migration failed.

ReadFailed(Error)

Reading the committed delivery sequence failed.

InvalidPersistedValue

A persisted delivery value cannot satisfy the public delivery contract.

Fields

field: &'static str

Name of the persisted field that could not be represented.

detail: String

Conversion failure detail.

Trait Implementations

impl Debug for PostgresProjectionSourceError

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

Formats the value using the given formatter.

impl Display for PostgresProjectionSourceError

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

Formats the value using the given formatter.

impl Error for PostgresProjectionSourceError

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.
