Enum MemoryError 

pub enum MemoryError {
    InvalidConfig(&'static str),
    Exhausted {
        class: MemoryClass,
        requested: u64,
        available: u64,
    },
    LowPriorityRejected {
        class: MemoryClass,
    },
}

Errors of governor configuration and reservation.

Variants

InvalidConfig(&'static str)

The GovernorConfig failed validation.

Exhausted

The reservation did not fit within the class budget, the node maximum, or (for non-reserved classes) the reserved floor.

Fields

class: MemoryClass

Requesting pool.

requested: u64

Requested bytes.

available: u64

Bytes the requester could still have been granted.

LowPriorityRejected

Low-priority work rejected under pressure (S1E-003 escalation step 1).

Fields

class: MemoryClass

Requesting pool.

Trait Implementations

impl Clone for MemoryError

fn clone(&self) -> MemoryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl Display for MemoryError

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

Formats the value using the given formatter.

impl Eq for MemoryError

impl Error for MemoryError

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 PartialEq for MemoryError

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

Equality operator ==.

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

Inequality operator !=.
