Struct Delimiters

pub struct Delimiters { /* private fields */ }

Represents the three delimiter types used in X12 EDI transactions.

X12 delimiters control how segments, elements, and sub-elements are separated in the EDI data. The standard default delimiters are:

• Segment terminator: ~
• Element separator: *
• Sub-element separator: :

Implementations

impl Delimiters

pub fn new( segment_terminator: u8, element_separator: u8, sub_element_separator: u8, ) -> Delimiters

Creates a new Delimiters instance with the specified values.

Arguments

• segment_terminator - Character used to terminate segments
• element_separator - Character used to separate elements
• sub_element_separator - Character used to separate sub-elements

pub fn from_isa(isa_segment: &[u8]) -> Result<Delimiters, DelimiterError>

Extracts delimiters from an ISA segment.

The ISA segment is the first segment in an X12 file and contains the delimiter information.

• Element separator is at position 3
• Sub-element separator is at position 104
• Segment terminator is at position 105

Arguments

• isa_segment - Byte slice containing the ISA segment

Returns

• Result<Delimiters, DelimiterError> - Delimiters on success, error on failure

Errors

Returns DelimiterError::InvalidIsaLength if the ISA segment is too short

pub fn segment_terminator(&self) -> u8

Returns the segment terminator character.

pub fn element_separator(&self) -> u8

Returns the element separator character.

pub fn sub_element_separator(&self) -> u8

Returns the sub-element separator character.

pub fn are_valid(&self) -> bool

Validates that all three delimiters are distinct.

In X12 EDI, all delimiters must be different characters to avoid ambiguity.

Returns

• bool - True if all delimiters are unique, false otherwise

Trait Implementations

impl Clone for Delimiters

fn clone(&self) -> Delimiters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Delimiters

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

Formats the value using the given formatter.

impl Default for Delimiters

fn default() -> Delimiters

Creates a Delimiters instance with the standard default values.

impl PartialEq for Delimiters

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