Enum ResourceError 

pub enum ResourceError {
    Invalid(&'static str),
    Exhausted {
        budget: &'static str,
        requested: usize,
        used: usize,
        limit: usize,
    },
    DifferentTree,
    InvalidOwnership,
}

Errors from managed-byte accounting: invalid budgets, exhausted limits, and reservation ownership violations.

Variants

Invalid(&'static str)

The requested budget or limit is invalid.

Exhausted

A budget could not admit the requested bytes.

Fields

budget: &'static str

Budget that refused the request.

requested: usize

Bytes requested.

used: usize

Bytes currently charged.

limit: usize

Configured byte limit.

DifferentTree

The two reservations belong to different resource trees.

InvalidOwnership

A reservation operation would exceed the bytes it owns.

Trait Implementations

impl Clone for ResourceError

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 ResourceError

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

Formats the value using the given formatter.

impl Display for ResourceError

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

Formats the value using the given formatter.

impl Eq for ResourceError

impl Error for ResourceError

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 ResourceError

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

Equality operator ==.

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

Inequality operator !=.
