Enum AlphabetError 

pub enum AlphabetError {
    InvalidId {
        value: String,
        reason: &'static str,
    },
    Empty {
        id: AlphabetId,
    },
    DuplicateSymbol {
        id: AlphabetId,
        first: usize,
        duplicate: usize,
    },
    DuplicateId(AlphabetId),
}

Failure while defining an alphabet or registering its stable identity.

Variants

InvalidId

An alphabet id was empty or did not use the stable portable syntax.

Fields

value: String

Rejected id text.

reason: &'static str

Specific syntax violation.

Empty

A finite musical alphabet contained no symbols.

Fields

id: AlphabetId

Stable id of the empty alphabet.

DuplicateSymbol

The same symbol occupied two canonical alphabet positions.

Fields

id: AlphabetId

Stable alphabet id.

first: usize

First canonical position.

duplicate: usize

Repeated canonical position.

DuplicateId(AlphabetId)

A registry already contained the stable id being inserted.

Trait Implementations

impl Eq for AlphabetError

impl Error for AlphabetError

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
