Enum DavError 

pub enum DavError {
    Unauthorized,
    Forbidden,
    NotFound,
    BadRequest(String),
    Conflict,
    PreconditionFailed,
    MethodNotAllowed,
    ServiceUnavailable,
    ServerError(String),
}

Errors a DAV handler can return.

Most variants map 1:1 to HTTP status codes; ServerError is the catch-all for anything the store impl can’t classify.

Variants

Unauthorized

401 — auth required. Server-side wrapper is expected to add the WWW-Authenticate header.

Forbidden

403 — authenticated but not permitted.

NotFound

404 — resource doesn’t exist.

BadRequest(String)

400 — malformed request body / unsupported parameters.

Conflict

409 — server-side semantic conflict (e.g. parent collection missing).

PreconditionFailed

412 — If-Match / If-None-Match precondition failed.

MethodNotAllowed

405 — verb not allowed on this resource.

ServiceUnavailable

503 — backing store unavailable (e.g. database down).

ServerError(String)

500 — anything else. Description is for the server log, not the client.

Implementations

impl DavError

pub fn to_dav_response(&self) -> DavResponse

Convert into the minimal DavResponse a server can serve directly.

Bodies are short, plain-text, ASCII; suitable as a fallback when the server-side adapter doesn’t want to do custom error formatting.

Trait Implementations

impl Clone for DavError

fn clone(&self) -> DavError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DavError

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

Formats the value using the given formatter.

impl Display for DavError

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

Formats the value using the given formatter.

impl Error for DavError

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>)
