Enum Error 

pub enum Error {
    NotFound,
    Invalid,
    Conflict,
    Db(Error),
    Unavailable(String),
    Other(String),
}

Errors returned by videre-api operations. Each consumer maps these to its own convention (axum -> StatusCode, other embedders -> their own error type).

Variants

NotFound

The target row/label does not exist.

Invalid

Caller-supplied input was rejected (e.g. an empty label after sanitizing).

Conflict

The thing being mutated changed underneath the caller (stale question, moved face, different active profile). Retry with fresh state.

Db(Error)

Underlying database failure.

Unavailable(String)

The library is momentarily unavailable: its root no longer names the library the server bound to, or exclusive maintenance holds it. Distinct from a permanent failure so the caller can map it to a retryable status (503) rather than a 500.

Other(String)

Any other failure surfaced as a plain message (e.g. from videre-core functions that return anyhow::Error, like pipeline_runs).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
