Enum LLError 

pub enum LLError {
    Transport(Box<dyn Error + Send + Sync>),
    NotSupported,
    ResourceExhausted,
    Protocol {
        code: u32,
        detail: Bytes,
    },
}

Errors at the LL (low-level) layer.

These are transport and system-level errors only. Semantic errors (invalid paths, type mismatches, codec failures) belong in higher layers.

Variants

Transport(Box<dyn Error + Send + Sync>)

Generic I/O or transport failure.

Use this for network errors, file I/O errors, IPC failures, etc.

NotSupported

The operation is not supported by this store.

For example, writing to a read-only store.

ResourceExhausted

Resource limit exceeded.

Memory exhaustion, too many open handles, etc.

Protocol

Protocol-specific error with a numeric code.

The code and detail are opaque to the LL layer. Higher layers or the transport protocol define their meaning.

Fields

code: u32

Protocol-specific error code.

detail: Bytes

Optional detail bytes (error message, structured error, etc.)

Trait Implementations

impl Debug for LLError

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

Formats the value using the given formatter.

impl Display for LLError

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

Formats the value using the given formatter.

impl Error for LLError

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 From<Error> for LLError

fn from(e: Error) -> Self

Converts to this type from the input type.
