Enum AssetError 

pub enum AssetError {
    Io(Error),
    Serialization(Error),
    Config(String),
    NotFound(String),
    CacheDir(String),
    Poisoned(String),
    Core(Error),
}

Errors that can occur during asset cache operations.

Variants

Io(Error)

Underlying filesystem I/O failure.

Serialization(Error)

Failed to (de)serialize JSON while reading / writing the index.

Config(String)

Failed to parse a human-readable size / duration in configuration.

NotFound(String)

The requested asset was not present in the cache index.

CacheDir(String)

The cache directory was unreachable or could not be created.

Poisoned(String)

The in-memory index mutex was poisoned by a panic in another thread. Callers can decide whether to recover (rebuild index) or bubble the error up to the user.

Core(Error)

Anything surfaced from devboy_core::Error.

Implementations

impl AssetError

pub fn config(msg: impl Into<String>) -> Self

Create a new configuration error.

pub fn cache_dir(msg: impl Into<String>) -> Self

Create a new cache directory error.

pub fn not_found(id: impl Into<String>) -> Self

Create a new not-found error.

pub fn poisoned(msg: impl Into<String>) -> Self

Create a new poisoned-mutex error.

Trait Implementations

impl Debug for AssetError

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

Formats the value using the given formatter.

impl Display for AssetError

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

Formats the value using the given formatter.

impl Error for AssetError

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.
