Struct PromoteError 

pub struct PromoteError {
    pub type_name: &'static str,
    pub memory: Option<MemoryLimitExceeded>,
}

Returned when a Value cannot be promoted to SharedValue.

Fields

type_name: &'static str

memory: Option<MemoryLimitExceeded>

Set when the value is promotable but the governor refused its shared allocation (strict mode).

Implementations

impl PromoteError

pub fn not_promotable(type_name: &'static str) -> Self

pub fn memory_limit(type_name: &'static str, error: MemoryLimitExceeded) -> Self

The governor refused the shared allocation for a type_name value.

impl PromoteError

pub fn into_value_error(self) -> ValueError

The ValueError a builtin reports for this failure: the memory refusal itself, or Other with the message.

Trait Implementations

impl Clone for PromoteError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PromoteError

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

Formats the value using the given formatter.

impl Display for PromoteError

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

Formats the value using the given formatter.

impl Error for PromoteError

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.
