Enum RegionCreateError 

pub enum RegionCreateError {
    ParentNotFound(RegionId),
    ParentClosed(RegionId),
    ParentAtCapacity {
        region: RegionId,
        limit: usize,
        live: usize,
    },
    ResourcePressure {
        requested_priority: RegionPriority,
        reason: String,
    },
}

Errors that can occur when creating a child region.

Variants

ParentNotFound(RegionId)

The parent region does not exist.

ParentClosed(RegionId)

The parent region is closed or draining and cannot accept new children.

ParentAtCapacity

The parent region has reached its admission limit for children.

Fields

region: RegionId

The parent region that rejected the child.

limit: usize

The configured admission limit.

live: usize

The number of live children at the time of rejection.

ResourcePressure

Resource pressure prevents creating new regions.

Fields

requested_priority: RegionPriority

The priority requested for the new region.

reason: String

The reason for rejection due to resource pressure.

Trait Implementations

impl Clone for RegionCreateError

fn clone(&self) -> RegionCreateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegionCreateError

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

Formats the value using the given formatter.

impl Display for RegionCreateError

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

Formats the value using the given formatter.

impl Error for RegionCreateError

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<RegionCreateError> for SupervisorSpawnError

fn from(value: RegionCreateError) -> Self

Converts to this type from the input type.

impl PartialEq for RegionCreateError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
