Struct ReadPreset 

pub struct ReadPreset {
    pub name: &'static str,
    pub reader: &'static str,
    pub choices: &'static [(&'static str, &'static str)],
    pub note: &'static str,
}

A combination of scope choices a reader’s crate offers by name: hand-picked and labelled so, with what is known of why. Nothing applies it: a caller names the preset it wants, and the choices are then the caller’s, stated.

Fields

name: &'static str

The preset’s name, stable within its reader.

reader: &'static str

The reader scope (ReadScopeSpec::name) whose options it states.

choices: &'static [(&'static str, &'static str)]

Option and value, each an option the scope declares and a value it accepts.

note: &'static str

What the choices are and the evidence for them, saying where they are observed and where only picked.
