Enum RagError 

pub enum RagError {
    Config(String),
    Conversion(String),
    Embedding(String),
    Store(String),
    Llm(String),
    Source(String),
    Queue(String),
    Http(String),
    Io(Error),
    Json(Error),
    FeatureDisabled(String, String),
}

Every fallible operation in the crate surfaces one of these.

Implementations

impl RagError

pub fn config(msg: impl Display) -> Self

Helper to build a RagError::Config from anything printable.

Trait Implementations

impl Debug for RagError

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

Formats the value using the given formatter.

impl Display for RagError

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

impl Error for RagError

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
