Enum PatchError 

pub enum PatchError {
    BaseMismatch {
        expected: String,
        actual: String,
    },
}

Why an ops document could not be applied.

One refusal today, and it is the one worth naming: the caller supplied a base that is provably not the one the ops were extracted from. It used to be a String carrying both hashes inside a sentence, so the only way to tell this refusal from any other was to read the prose. Both operands now travel as fields, and a caller can decide (re-extract? drop the base? stop?) by matching.

Variants

BaseMismatch

The supplied base does not hash to what the ops were extracted against.

Fields

expected: String

The digest the document declares.

actual: String

The digest the supplied base actually has.

Trait Implementations

impl Eq for PatchError

impl Error for PatchError

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>)

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

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

impl PartialEq for PatchError

fn eq(&self, other: &PatchError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool
