Enum AgentDbError 

pub enum AgentDbError {
    Sqlite(Error),
    Serialization(String),
    CollectionNotFound(String),
    DimensionMismatch {
        expected: usize,
        got: usize,
    },
    NodeNotFound(String),
    EdgeNotFound {
        src: String,
        dst: String,
    },
    SchemaMigration,
    Corruption(String),
    InvalidArgument(String),
}

All errors that AgentDB operations can produce.

Every public API function returns Result<T> which aliases std::result::Result<T, AgentDbError>.

Variants

Sqlite(Error)

Underlying SQLite operation failed.

Serialization(String)

JSON (de)serialization failed; the message describes what went wrong.

CollectionNotFound(String)

The named vector collection does not exist in the database.

DimensionMismatch

The caller supplied a vector whose length differs from the collection’s declared dimensionality.

Fields

expected: usize

got: usize

NodeNotFound(String)

A memory graph node with the given ID does not exist.

EdgeNotFound

A directed edge between the given nodes does not exist.

Fields

src: String

dst: String

SchemaMigration

The on-disk schema version is newer or older than this library expects. Run agentdb migrate to bring the database up to date.

Corruption(String)

Low-level database corruption was detected (checksum failure, unexpected NULL in a required column, etc.).

InvalidArgument(String)

A caller-supplied argument was out of range or otherwise invalid.

Trait Implementations

impl Debug for AgentDbError

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

Formats the value using the given formatter.

impl Display for AgentDbError

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

Formats the value using the given formatter.

impl Error for AgentDbError

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 AgentDbError

fn from(source: Error) -> Self

Converts to this type from the input type.
