Enum OmniError 

pub enum OmniError {
    Compiler(NanoError),
    Lance(String),
    DataFusion(String),
    Io(Error),
    Manifest(ManifestError),
    MergeConflicts(Vec<MergeConflict>),
    Policy(String),
    AlreadyInitialized {
        uri: String,
    },
}

Variants

Compiler(NanoError)

Lance(String)

DataFusion(String)

Io(Error)

Manifest(ManifestError)

MergeConflicts(Vec<MergeConflict>)

Policy(String)

Engine-layer policy enforcement (MR-722). Wraps either a policy denial (“you can’t do that”) or a policy-evaluation failure (“the policy engine itself blew up”). The HTTP layer maps denials to 403 and evaluation failures to 500; CLI and embedded callers can match on this variant directly.

AlreadyInitialized

Omnigraph::init was called against a URI that already holds schema artifacts from a previous init. Strict mode (the default) fails fast with this error before touching disk so an existing graph’s metadata cannot be overwritten or destroyed. Operators who actually want to overwrite pass InitOptions { force: true } (CLI: omnigraph init --force).

Fields

uri: String

Trait Implementations

impl Debug for OmniError

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

Formats the value using the given formatter.

impl Display for OmniError

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

Formats the value using the given formatter.

impl Error for OmniError

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 OmniError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<NanoError> for OmniError

fn from(source: NanoError) -> Self

Converts to this type from the input type.
