Represents an error that can occur when parsing a gitignore file.

Variants

Partial(Vec<Error>)

A collection of “soft” errors. These occur when adding an ignore file partially succeeded.

WithLineNumber

An error associated with a specific line number.

Fields

line: u64

The line number.

err: Box<Error>

The underlying error.

WithPath

An error associated with a particular file path.

Fields

path: PathBuf

The file path.

err: Box<Error>

The underlying error.

WithDepth

An error associated with a particular directory depth when recursively walking a directory.

Fields

depth: usize

The directory depth.

err: Box<Error>

The underlying error.

Loop

An error that occurs when a file loop is detected when traversing symbolic links.

Fields

ancestor: PathBuf

The ancestor file path in the loop.

child: PathBuf

The child file path in the loop.

Io(Error)

An error that occurs when doing I/O, such as reading an ignore file.

Glob

An error that occurs when trying to parse a glob.

Fields

glob: Option<String>

The original glob that caused this error. This glob, when available, always corresponds to the glob provided by an end user. e.g., It is the glob as written in a .gitignore file.

(This glob may be distinct from the glob that is actually compiled, after accounting for gitignore semantics.)

err: String

The underlying glob error as a string.

UnrecognizedFileType(String)

A type selection for a file type that is not defined.

InvalidDefinition

A user specified file type definition could not be parsed.

Implementations

impl Error

pub fn is_partial(&self) -> bool

Returns true if this is a partial error.

A partial error occurs when only some operations failed while others may have succeeded. For example, an ignore file may contain an invalid glob among otherwise valid globs.

pub fn is_io(&self) -> bool

Returns true if this error is exclusively an I/O error.

pub fn io_error(&self) -> Option<&Error>

Inspect the original std::io::Error if there is one.

None is returned if the Error doesn’t correspond to an std::io::Error. This might happen, for example, when the error was produced because a cycle was found in the directory tree while following symbolic links.

This method returns a borrowed value that is bound to the lifetime of the Error. To obtain an owned value, the into_io_error can be used instead.

This is the original std::io::Error and is not the same as impl From<Error> for std::io::Error which contains additional context about the error.

pub fn into_io_error(self) -> Option<Error>

Similar to io_error except consumes self to convert to the original std::io::Error if one exists.

pub fn depth(&self) -> Option<usize>

Returns a depth associated with recursively walking a directory (if this error was generated from a recursive directory iterator).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 Error

fn from(err: Error) -> Error

Converts to this type from the input type.
