Struct Selection 

pub struct Selection {
    pub field: &'static str,
    pub value: &'static str,
}

How a group is chosen when it is one of several stored alternatives: writing value to field makes the instrument play this one.

Not a relevance condition. The other alternatives stay relevant — a stored preset the instrument is not playing is still state the panel offers — where a group whose Group::when fails is one the instrument is not using at all.

Fields

field: &'static str

The field that chooses between the sibling groups.

value: &'static str

The value that selects this group, spelled as Field::value spells it.

Implementations

impl Selection

pub fn selected(&self, fields: &[Field]) -> bool

Whether the body’s current value selects this group.

Trait Implementations

impl Debug for Selection

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

Formats the value using the given formatter.
