Enum MemoryError 

pub enum MemoryError {
    InvalidBudget(String),
    UnknownCapacity {
        resource: String,
        budget: MemoryBudget,
        basis: &'static str,
    },
    BudgetExceeded {
        resource: String,
        requested: u64,
        remaining: u64,
    },
}

Errors produced while discovering or reserving memory.

Variants

InvalidBudget(String)

A budget string or percentage is invalid.

UnknownCapacity

A percentage cannot be resolved because capacity telemetry is unavailable.

Fields

resource: String

Resource label.

budget: MemoryBudget

Requested budget.

basis: &'static str

Missing capacity basis.

BudgetExceeded

A reservation exceeds the effective pool limit.

Fields

resource: String

Resource label.

requested: u64

Requested reservation.

remaining: u64

Remaining reservable bytes.

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<(), Error>

Formats the value using the given formatter.

impl Display for MemoryError

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

Formats the value using the given formatter.

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 From<MemoryError> for RuntimeError

fn from(source: MemoryError) -> Self

Converts to this type from the input type.

impl PartialEq for MemoryError

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

Equality operator ==.

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

Inequality operator !=.
