Struct KvBudgetError 

pub struct KvBudgetError {
    pub binding: Ceiling,
    pub estimated_bytes: u64,
    pub limit_bytes: u64,
    pub detail: String,
}

A structured refusal: what it would have cost, what the ceiling was, and which ceiling. Deliberately not an allocation failure – the whole point of computing this before the load is that nobody has to read an OOM to find out.

Fields

binding: Ceiling

estimated_bytes: u64

limit_bytes: u64

detail: String

Implementations

impl KvBudgetError

pub fn code(&self) -> &'static str

pub fn overage_bytes(&self) -> u64

Bytes over the ceiling (saturating, so a fit reads as 0).

Trait Implementations

impl Clone for KvBudgetError

fn clone(&self) -> KvBudgetError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KvBudgetError

impl Eq for KvBudgetError

impl Error for KvBudgetError

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
