Enum PgError 

pub enum PgError {
    Postgres(Error),
    TypeConversion(String),
    Tls(String),
    ConstraintViolation {
        constraint: String,
        detail: String,
    },

}

Errors that can arise within the oxisql-postgres backend.

This is a backend-private type. Public API surfaces translate these errors into oxisql_core::OxiSqlError.

Variants

Postgres(Error)

Error during connection or wire-protocol communication.

TypeConversion(String)

A column value could not be mapped to the requested OxiSQL type.

Tls(String)

TLS setup failed.

ConstraintViolation

A unique/foreign-key/check constraint was violated.

Fields

constraint: String

The PostgreSQL constraint name.

detail: String

Detail from the server error.

Timeout(String)

The operation timed out.

PoolExhausted(String)

The connection pool is exhausted.

Copy(String)

A COPY IN or COPY OUT protocol error.

Notify(String)

A LISTEN/NOTIFY error (invalid channel name or unsupported connection type).

Connection(String)

A connection-level error (e.g. cancel request failed).

Replication(String)

A replication-protocol error (slot management, negotiation, or unexpected server state).

Protocol(String)

A malformed or truncated wire-protocol message was received (decoder bounds-check failure).

Trait Implementations

impl Debug for PgError

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

Formats the value using the given formatter.

impl Display for PgError

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

Formats the value using the given formatter.

impl Error for PgError

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 PgError

impl From<PgError> for OxiSqlError

fn from(e: PgError) -> Self
