The different ways that Monument can fail.

Variants

MethodNotFound

The given title couldn’t be found in the Central Council library. Each suggestions is paired with its ‘edit distance’ (i.e. a metric of how different it is from the requested title)

Fields

title: String

suggestions: Vec<(String, usize)>

MethodPnParse

Some method’s place notation failed to parse

Fields

name: String

place_notation_string: String

error: PnBlockParseError

CustomCourseMaskParse

Some course mask couldn’t be parsed.

Fields

method_title: String

mask_str: String

error: ParseError

DifferentStartEndRowInMultipart

Different start/end rows were specified in a multi-part

UndefinedLabel

Some Call refers to a label that doesn’t exist

Fields

call_name: String

label: String

NoMethods

No methods were defined

DuplicateShorthand

Two Methods use the same shorthand

Fields

shorthand: String

title1: String

title2: String

WrongCallingPositionsLength

Some Call doesn’t have enough calling positions to cover the Stage

Fields

call_name: String

calling_position_len: usize

stage: Stage

DuplicateCall

Two Calls have the same lead location and name

Fields

symbol: String

label: String

pn1: PlaceNot

pn2: PlaceNot

SizeLimit(usize)

The given maximum graph size limit was reached

InconsistentStroke

The same chunk of ringing could start at two different strokes, and some MusicType relies on the strokes always being the same

UnachievableLength

The requested length range isn’t achievable

Fields

requested_range: RangeInclusive<TotalLength>

next_shorter_len: Option<usize>

next_longer_len: Option<usize>

UnachievableMethodCount

Some method range isn’t achievable

Fields

method_name: String

requested_range: OptionalRangeInclusive

next_shorter_len: Option<usize>

next_longer_len: Option<usize>

TooMuchMethodCount

The total of the minimum method counts is longer than the composition

Fields

min_total_method_count: usize

max_length: usize

TooLittleMethodCount

Fields

max_total_method_count: usize

min_length: usize

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
