Enum Value 

pub enum Value {
    Str(String),
    Literal(String),
}

A keyword value together with how it should be serialized.

XISF stores FITS keyword values with FITS formatting conventions: string values are single-quoted, everything else (numbers, logicals) is bare. The distinction is preserved so a value round-trips as the same kind it was.

use xisf_header::Value;

let string_value = Value::Str("Master Dark".to_owned());
let literal_value = Value::Literal("300".to_owned());
assert_eq!(string_value.text(), "Master Dark");
assert_eq!(literal_value.text(), "300");

Variants

Str(String)

A string value (serialized single-quoted, ''-escaped).

Literal(String)

A bare literal — number, logical, or any pre-formatted token.
