Enum InvalidIfMatch 

pub enum InvalidIfMatch {
    RepeatedHeader,
    Empty,

    WeakValidator,
    List,
    Malformed,
    PrefixMismatch,

}

Why an If-Match value is not one strong ETag for the resource.

Variants

RepeatedHeader

The request carries more than one If-Match header.

Empty

The header value is empty or only whitespace.

NonAscii

The header value contains bytes outside visible ASCII, space, and tab.

Wildcard

The header value is *.

WeakValidator

The ETag is weak (W/"...").

List

The header value lists more than one ETag.

Malformed

The header value is not a quoted entity tag.

PrefixMismatch

The ETag does not start with the route’s prefix.

InvalidRevision

The revision is not canonical decimal digits.

RevisionOutOfRange

The revision is larger than Revision::MAX.

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
