Enum MemoryBudgetError 

pub enum MemoryBudgetError {
    Zero,
    Exhausted {
        requested: usize,
        available: usize,
    },
}

Failure to construct or reserve an execution-memory budget.

Variants

Zero

A zero-byte budget cannot make forward progress.

Exhausted

The context has insufficient unreserved capacity.

Fields

requested: usize

Bytes requested by the operation.

available: usize

Bytes still available at the time of the attempt.

Trait Implementations

impl Eq for MemoryBudgetError

impl Error for MemoryBudgetError

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<MemoryBudgetError> for StructureBatchError
