Enum RoleProjectionError 

pub enum RoleProjectionError {
    Limit {
        limit: usize,
        required: usize,
    },
    Arena(ArenaError),
}

A failed bounded role-evidence projection.

Variants

Limit

The requested projection would exceed its explicit row limit.

Fields

limit: usize

Maximum admitted role rows.

required: usize

Number of live managed objects requiring rows.

Arena(ArenaError)

The arena rejected the safepoint.

Trait Implementations

impl Clone for RoleProjectionError

fn clone(&self) -> RoleProjectionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoleProjectionError

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

Formats the value using the given formatter.

impl Display for RoleProjectionError

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

Formats the value using the given formatter.

impl Eq for RoleProjectionError

impl Error for RoleProjectionError

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<ArenaError> for RoleProjectionError

fn from(error: ArenaError) -> Self

Converts to this type from the input type.

impl PartialEq for RoleProjectionError

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

Equality operator ==.

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

Inequality operator !=.
