Invalid grit diff argument combinations or revision parsing failures.

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.

StagedAndUnstaged

--staged and --unstaged together.

StagedWithRevisions

--staged with commit arguments or --against.

UnstagedWithRevisions

--unstaged with commit arguments or --against.

TooManyRevisions

More than two commit-ish positionals (excluding range syntax in one token).

AgainstWithCommits

--against with commit positionals.

RangeWithSecondRevision

Second positional after a range token should be passed after --.

NoWorkTree

Path limits for a working-tree comparison in a repository without a work tree.

UnresolvedRevision

A revision operand does not name an object.

Fields

spec: String

The operand as given.

source: Box<Error>

Why resolution failed.

NotACommit

A revision (after peeling tags) names a tree or blob instead of a commit.

Fields

oid: ObjectId

The tree or blob the revision led to.

NoMergeBase

A three-dot range whose sides share no history.

MultipleMergeBases

A three-dot range whose sides have more than one merge base (criss-cross history).

Pathspec(PathspecResolveError)

A pathspec could not be parsed or normalized.

Library(Box<Error>)

Range endpoint resolution, object reads, or a working-tree pathspec matching nothing (Error::PathspecNoMatch).

Trait Implementations

impl Debug for ResolveDiffArgumentsError

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

Formats the value using the given formatter.

impl Display for ResolveDiffArgumentsError

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

Formats the value using the given formatter.

impl Error for ResolveDiffArgumentsError

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<Error> for ResolveDiffArgumentsError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<PathspecResolveError> for ResolveDiffArgumentsError

fn from(source: PathspecResolveError) -> Self

Converts to this type from the input type.
