Enum PgGraphMemoryError 

#[non_exhaustive]
pub enum PgGraphMemoryError {
    Sqlx(Error),
    Malformed(String),
    Config(String),
    Codec(Error),
}

Errors that can surface from PgGraphMemory.

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.

Sqlx(Error)

Underlying sqlx / Postgres failure.

Malformed(String)

Server returned a row shape inconsistent with what the schema migration installed. Indicates either a stale auto_migrate=false deployment or external schema drift.

Config(String)

Configuration error — invalid connection string, missing pool / pool URL, unsafe table name.

Codec(Error)

JSON encode / decode failure on a node / edge payload.

Trait Implementations

impl Debug for PgGraphMemoryError

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

Formats the value using the given formatter.

impl Display for PgGraphMemoryError

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

Formats the value using the given formatter.

impl Error for PgGraphMemoryError

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.
