Struct Cancel 

pub struct Cancel {
    pub attributes: CancelAttributes,
    pub content: Fifths,
}

The Cancel element indicates that the old key signature should be cancelled before the new one appears.

This will always happen when changing to C major or A minor and need not be specified then. The Cancel element value matches the fifths value of the cancelled key signature (e.g., a cancel of -2 will provide an explicit cancellation for changing from B flat major to F major).

Fields

attributes: CancelAttributes

Element-specific attributes

content: Fifths

Element-specific content

Trait Implementations

impl Debug for Cancel

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

Formats the value using the given formatter.

impl Eq for Cancel

impl PartialEq for Cancel

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
