Struct ControlField 

pub struct ControlField {
    pub tag: FieldTag,
    pub data: String,
}

The first fields of a MARC record represent control data. Unlike the variable data fields, they are simple blob of ASCII content, although some of them are encoded with a specific scheme (for example, some of them are pipe-separated values)

Fields

tag: FieldTag

data: String

Trait Implementations

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