Enum DestinationPreconditionError 

#[non_exhaustive]
pub enum DestinationPreconditionError {
    PreconditionsRequireReplace {
        field: &'static str,
    },
    RevisionRequiresInode {
        revision_field: &'static str,
        inode_field: &'static str,
    },
}

Why a destination precondition is not a valid request.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PreconditionsRequireReplace

A create-only operation supplied a replacement precondition.

Fields

field: &'static str

First supplied expectation field, with inode before revision.

RevisionRequiresInode

A revision precondition did not name the inode whose revision it checks.

Fields

revision_field: &'static str

Revision field supplied by the request.

inode_field: &'static str

Inode field required beside the revision.

impl Eq for DestinationPreconditionError

impl Error for DestinationPreconditionError

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
