Struct Copybook 

pub struct Copybook {
    pub record_name: String,
    pub encoding: String,
    pub fields: Vec<FieldDecl>,
}

A copybook: the record name, the declared character encoding (informational, carried into the packet), and the top-level fields in order.

Fields

record_name: String

The 01-level record name.

encoding: String

The declared character encoding, e.g. ascii or ebcdic-cp-us. Carried into the packet as encoding; kobold-csv decodes display bytes as-is and does not transcode.

fields: Vec<FieldDecl>

The top-level fields, in record order.

Implementations

impl Copybook

pub fn record_length(&self) -> usize

The total declared record length = sum of top-level field lengths.

pub fn leaf_fields(&self) -> Vec<&FieldDecl>

A flat, in-order list of the LEAF fields (groups recursed into their children). CSV is inherently a flat tabular format: a row is a sequence of columns, so the export/parse courts work over the leaf fields in record order. This is the bridge from the (possibly nested) copybook tree to columns.

pub fn canonical_bytes(&self) -> Vec<u8>

A stable, canonical byte serialization of the copybook layout, used as the input to copybook_hash. Deterministic: a pure function of the structure (names/pics/offsets/lengths/kinds), independent of insertion-time state.

Trait Implementations

impl Clone for Copybook

fn clone(&self) -> Copybook

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Copybook

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

Formats the value using the given formatter.

impl Eq for Copybook

impl PartialEq for Copybook

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