Failure while parsing or resolving a -L line range specification.

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.

InvalidSpec

The spec could not be parsed or had trailing garbage.

Fields

spec: String

Raw -L argument.

detail: String

Human-readable detail.

InvalidLineNumber

A line number was zero or negative.

Fields

spec: String

Raw -L argument.

line: i64

Offending number.

EmptyRange

Relative end ,+0 / ,-0 style empty span.

Fields

spec: String

Raw -L argument.

InvalidRegex

POSIX regex compilation failed.

Fields

pattern: String

Pattern (without slashes).

detail: String

regcomp / engine message.

RegexNoMatch

Regex did not match from the anchor line.

Fields

pattern: String

Pattern (without slashes).

start_line: usize

1-based anchor line searched from.

FuncnameNoMatch

:funcname pattern did not match a function header.

Fields

pattern: String

Funcname search pattern.

start_line: usize

1-based anchor line searched from.

FuncnameInvalidPattern

:funcname pattern is invalid.

Fields

pattern: String

Funcname search pattern.

detail: String

Detail.

FuncnameAtEof

:funcname match ended at EOF (Git rejects blaming through EOF for func ranges).

Fields

pattern: String

Funcname search pattern.

OutOfRange

Resolved range lies outside the file.

Fields

spec: String

Raw -L argument.

lines: usize

Line count in the file at the blamed revision.

Trait Implementations

impl Debug for LineRangeError

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

Formats the value using the given formatter.

impl Display for LineRangeError

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

Formats the value using the given formatter.

impl Eq for LineRangeError

impl Error for LineRangeError

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 LineRangeError

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

Equality operator ==.

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

Inequality operator !=.
