Enum ErrorKind 

#[non_exhaustive]
pub enum ErrorKind {
    Unexpected,
    InvalidHandle,
    OutOfMemory,
    InvalidInput,
    IoError,
    InvalidState,
    NotImplemented,
    UnsupportedType,
    NonConvergence,
}

Categorisation of cuGraph and library-level errors.

Each variant describes what the caller should do. It does not name the dependency that failed. Variants that originate in the raw C API map to the corresponding CUGRAPH_* error codes; library-only variants cover Rust-side interop, lifecycle, and I/O boundaries.

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.

Unexpected

An unexpected or unknown error occurred (CUGRAPH_UNKNOWN_ERROR).

InvalidHandle

The resource handle is invalid (CUGRAPH_INVALID_HANDLE).

OutOfMemory

GPU memory allocation failed (CUGRAPH_ALLOC_ERROR).

InvalidInput

An input argument was invalid (CUGRAPH_INVALID_INPUT).

IoError

An external I/O operation failed.

InvalidState

A result invariant, lifecycle contract, or state transition failed (CUGRAPH_INVALID_STATE).

NotImplemented

The requested operation is not implemented (CUGRAPH_NOT_IMPLEMENTED).

UnsupportedType

The combination of types is not supported (CUGRAPH_UNSUPPORTED_TYPE_COMBINATION).

NonConvergence

An iterative algorithm reached its configured iteration bound.
