Enum PolicyError 

#[non_exhaustive]
pub enum PolicyError {
    Endpoint {
        reason: &'static str,
    },
    Query {
        reason: Cow<'static, str>,
    },
    UncheckableQuery {
        reason: &'static str,
    },
}

Why a request policy refused a request. Never carries the URL’s query string, a body or a token.

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.

Endpoint

The method, scheme, host, port or path is not one the policy allows.

Fields

reason: &'static str

Which rule refused it.

Query

The SQL text of a BigQuery query job was refused.

Fields

reason: Cow<'static, str>

Why (the policy’s own wording).

UncheckableQuery

A request to a BigQuery query endpoint whose SQL could not be isolated for checking (unreadable body, non-query or legacy-SQL job, or a field that changes what the SQL reads). Refused under every policy, so no query reaches BigQuery unchecked.

Fields

reason: &'static str

What was wrong.

Trait Implementations

impl Clone for PolicyError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PolicyError

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

Formats the value using the given formatter.

impl Display for PolicyError

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

Formats the value using the given formatter.

impl Eq for PolicyError

impl Error for PolicyError

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<PolicyError> for Error

fn from(source: PolicyError) -> Self

Converts to this type from the input type.

impl PartialEq for PolicyError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
