Enum Accidental 

pub enum Accidental {
    Natural,
    Sharp,
    DoubleSharp,
    Flat,
    DoubleFlat,
}

Represents an accidental alteration on a note.

Variants

Natural

Natural (no accidental). ‘♮’ symbol.

Sharp

Sharp accidental. ‘♯’, ‘#’ symbols.

DoubleSharp

Double sharp accidental. ‘𝄪’, ‘##’ symbols.

Flat

Flat accidental. ‘♭’, ‘b’ symbols.

DoubleFlat

Double flat accidental. ‘𝄫’, ‘bb’ symbols.

Implementations

impl Accidental

pub fn from_str(s: &str) -> Option<Self>

Tries to parse a string into an accidental. Case insensitive (for both flat alterations).

Examples

use chord_parser::chord::*;
 
assert_eq!(Some(Accidental::Flat), Accidental::from_str("B")); // Case insensitive
assert_eq!(Some(Accidental::DoubleFlat), Accidental::from_str("𝄫")); // Unicode works
assert_eq!(None, Accidental::from_str("as")); // Invalid input

Trait Implementations

impl Clone for Accidental

fn clone(&self) -> Accidental

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Accidental

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

Formats the value using the given formatter.

impl PartialEq for Accidental

fn eq(&self, other: &Accidental) -> 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.

impl ToString for Accidental

fn to_string(&self) -> String

Converts the given value to a String.

impl Eq for Accidental
