Enum GraphError 

pub enum GraphError {
    Io(Error),
    Serialization(String),
    Corruption(String),
    NotFound(&'static str),
    InvalidArgument(String),
    UnsupportedFeature(&'static str),
}

Errors that can occur during database operations.

Sombra uses this comprehensive error type to handle all failure modes from I/O issues to data corruption to invalid usage.

Variants

Io(Error)

I/O error from the underlying filesystem.

This can occur during file operations like reading, writing, or syncing data to disk.

Serialization(String)

Error during serialization or deserialization of data.

This occurs when data cannot be properly encoded or decoded, often due to format issues or buffer size problems.

Corruption(String)

Data corruption detected.

This is a critical error indicating that the database file or WAL has been corrupted. It may be recoverable with the repair tools, but data loss is possible.

NotFound(&'static str)

Requested resource was not found.

This occurs when trying to access a node or edge that doesn’t exist in the database.

InvalidArgument(String)

Invalid argument or operation.

This occurs for various reasons:

• Invalid configuration parameters
• Operations that violate database constraints
• Transaction limits exceeded
• Invalid property types for indexing

UnsupportedFeature(&'static str)

Feature is not yet implemented or supported.

This indicates that the requested operation is not available in the current version of Sombra.

Trait Implementations

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Error for GraphError

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 GraphError

fn from(source: Error) -> Self

Converts to this type from the input type.
