Enum MergeError 

#[non_exhaustive]
pub enum MergeError {
    Driver {
        line: String,
        reason: &'static str,
    },
    NoDriver {
        program: String,
    },
    Run {
        program: String,
        reason: String,
    },
    Unresolved {
        paths: Vec<RelPath>,
    },
    NothingToContinue,
    NothingToAbort,
    ChangedSince {
        paths: Vec<String>,
    },
    CorruptUndo {
        path: String,
    },
    Unmerged {
        path: RelPath,
    },
    Invalid {
        path: RelPath,
        reason: String,
    },
}

Why a merge cannot run, or its resolution cannot be installed.

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.

Driver

A driver line does not parse.

Fields

line: String

As configured.

reason: &'static str

The rule it breaks.

NoDriver

The driver’s program is not installed, or not on PATH.

Fields

program: String

The program.

Run

A driver program did not run to completion.

Fields

program: String

The program.

reason: String

Why it stopped.

Unresolved

Conflicts wait in .devset/conflicts/.

Fields

paths: Vec<RelPath>

Each conflicted path.

NothingToContinue

Resolutions were to be installed, and no conflict waits.

NothingToAbort

A conflicted run was to be taken back, and none is unfinished.

ChangedSince

Taking a conflicted run back would discard changes made since it.

Fields

paths: Vec<String>

Each changed file, relative to the target root.

CorruptUndo

A copy an update saved, to take it back, is missing or damaged.

Fields

path: String

The file it would restore, relative to the target root.

Unmerged

A resolution still has conflict markers.

Fields

path: RelPath

The conflicted path.

Invalid

A resolution does not pass its file’s check.

Fields

path: RelPath

The conflicted path.

reason: String

Why the check failed.

Trait Implementations

impl Clone for MergeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeError

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

Formats the value using the given formatter.

impl Display for MergeError

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

Formats the value using the given formatter.

impl Eq for MergeError

impl Error for MergeError

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 From<MergeError> for Error

fn from(source: MergeError) -> Self

Converts to this type from the input type.

impl PartialEq for MergeError

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

Equality operator ==.

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

Inequality operator !=.
