Enum CacheError 

pub enum CacheError {
    CidMismatch {
        expected: String,
        got: String,
    },
    EntryTooLarge(usize),
    CacheAtCapacity,
    EntryNotFound,
    TtlExpired,
}

Errors that can arise during cache operations.

Variants

CidMismatch

The provided CID does not match the CID derived from the data.

Fields

expected: String

got: String

EntryTooLarge(usize)

The entry’s payload exceeds the configured max_bytes limit.

CacheAtCapacity

The cache is at capacity and eviction could not free enough space.

EntryNotFound

No entry exists for the requested CID.

TtlExpired

The entry exists but its TTL has expired (it has been removed).

Trait Implementations

impl Clone for CacheError

fn clone(&self) -> CacheError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheError

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

Formats the value using the given formatter.

impl Display for CacheError

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

Formats the value using the given formatter.

impl Eq for CacheError

impl Error for CacheError

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 CacheError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
