Enum Certainty 

pub enum Certainty {
    Approximate,
    Uncertain,
    Priority,
}

How sure one part of a Date is: music21’s error strings, written as the symbols it writes them with.

Variants

Approximate

Near enough: music21’s approximate, written ~.

Uncertain

Not known to be right: music21’s uncertain, written ?.

Priority

music21’s priority, which its own _stripError reads off the bracket symbols <, {, > and }. It has no symbol of its own, and nothing of music21’s writes one.

Implementations

impl Certainty

pub fn name(self) -> &'static str

The name music21 gives it.

pub fn symbol(self) -> Option<char>

The symbol music21 writes after the part it marks, and nothing for priority: music21’s errorToSymbol.

pub fn named(name: &str) -> Option<Self>

What a name or a symbol stands for, read as music21’s errorToSymbol and _stripError read one.
