Enum OracleMcpError 

#[non_exhaustive]
pub enum OracleMcpError {
    Oracle(String),
    ObjectNotFound {
        name: String,
        fuzzy_matches: Vec<String>,
    },
    InsufficientPrivilege(String),
    ForbiddenStatement(String),
    LeaseRequired(String),
    OperatingLevelTooLow(String),
    ChallengeRequired(String),
    RuntimeStateRequired(String),
    Busy {
        retry_after_ms: u64,
    },
    InvalidArguments(String),
    PolicyDenied(String),
    Internal(String),
}

Library-side error type for ?-propagation across the oraclemcp core.

Distinct from ErrorEnvelope: this is the internal Result error; OracleMcpError::into_envelope renders the agent-facing shape at the tool boundary.

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.

Oracle(String)

A raw Oracle driver/DB error (its ORA- code is parsed on conversion).

ObjectNotFound

A referenced object was not found; carries near-miss candidates.

Fields

name: String

The object the caller asked for.

fuzzy_matches: Vec<String>

Near-miss candidates for the agent to consider.

InsufficientPrivilege(String)

The connected user lacks a required privilege.

ForbiddenStatement(String)

The statement failed the fail-closed classifier.

LeaseRequired(String)

A stateful operation needs a lease.

OperatingLevelTooLow(String)

Required operating level exceeds the current level.

ChallengeRequired(String)

A human step-up confirmation is required.

RuntimeStateRequired(String)

Live runtime state (e.g. an Oracle connection) is required.

Busy

Admission control rejected the call.

Fields

retry_after_ms: u64

Suggested wait before retrying.

InvalidArguments(String)

Invalid request arguments.

PolicyDenied(String)

A policy denied the call.

Internal(String)

An internal error.

Implementations

impl OracleMcpError

pub fn into_envelope(self) -> ErrorEnvelope

Render the agent-facing ErrorEnvelope.

Trait Implementations

impl Debug for OracleMcpError

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

Formats the value using the given formatter.

impl Display for OracleMcpError

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

Formats the value using the given formatter.

impl Error for OracleMcpError

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.
