Struct FieldDecl 

pub struct FieldDecl {
    pub name: String,
    pub pic: String,
    pub offset: usize,
    pub length: usize,
    pub kind: FieldKind,
}

A single field declaration from a copybook: a name, its PIC string, its byte offset within the record, its byte length, and its FieldKind.

Fields

name: String

The COBOL data name (e.g. CUST-NAME).

pic: String

The PIC clause text, kept verbatim for the audit packet (e.g. X(20), S9(5)V99).

offset: usize

Byte offset of the field within the record.

length: usize

Byte length of the field.

kind: FieldKind

The storage kind.

Implementations

impl FieldDecl

pub fn alnum( name: impl Into<String>, pic: impl Into<String>, offset: usize, length: usize, ) -> Self

An alphanumeric field.

pub fn numeric( name: impl Into<String>, pic: impl Into<String>, offset: usize, length: usize, scale: usize, signed: bool, ) -> Self

A numeric (zoned display) field.

pub fn group( name: impl Into<String>, offset: usize, children: Vec<FieldDecl>, ) -> Self

A group field with the given children. length is the sum of child lengths.

Trait Implementations

impl Clone for FieldDecl

fn clone(&self) -> FieldDecl

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldDecl

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

Formats the value using the given formatter.

impl Eq for FieldDecl

impl PartialEq for FieldDecl

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