Enum SearchError 

pub enum SearchError {
    IndexNotFound(String),
    AccessDenied(String),
    BadQuery(String),
    Backend(String),
}

Typed error returned by every SearchClientPlugin method.

Flat enum, not Result<_, String>, because classification matters: the capability dispatcher distinguishes “you asked for something that does not exist” from “you asked for something you cannot see” from “your query itself was malformed” from “the backend blew up”. Each variant carries a message for operator-facing logs; callers should match on the variant, not inspect the string.

Variants

IndexNotFound(String)

Index does not exist in the backend. Not the same as “empty index”; that returns Ok(SearchResults { hits: vec![], .. }).

AccessDenied(String)

Authentication or authorisation failed. Wrong API key, wrong role, wrong network. Distinct from Backend so the dispatcher can escalate credentials issues without paging on transport flakes.

BadQuery(String)

The query itself was malformed — syntax error, unsupported filter shape, out-of-range offset. Caller error, not backend fault. Recoverable by fixing the input.

Backend(String)

Everything else: network failure, backend 5xx, driver panic, timeout. Not classified further because the caller cannot recover from any of them except by retrying or alerting.

Trait Implementations

impl Clone for SearchError

fn clone(&self) -> SearchError

Returns a duplicate of the value.

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

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

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
