Struct ServiceStringAdvice 

pub struct ServiceStringAdvice {
    pub element_sep: u8,
    pub component_sep: u8,
    pub release_char: u8,
    pub decimal_mark: u8,
    pub segment_term: u8,
}

EDIFACT service string advice (UNA segment).

Defaults: + (element), : (component), ? (release), space (reserved), ' (segment).

Fields

element_sep: u8

Data element separator (default +)

component_sep: u8

Component data element separator (default :)

release_char: u8

Release character (default ?)

decimal_mark: u8

Decimal notation mark (default .; UNA byte 5, ISO 9735-1 §7.1). Not used by the tokenizer for splitting, but preserved for downstream use.

segment_term: u8

Segment terminator (default ')

Implementations

impl ServiceStringAdvice

pub fn from_bytes(input: &[u8]) -> Self

Parse a UNA header from the beginning of an EDIFACT interchange.

If no UNA is present, returns ServiceStringAdvice::default. Does not validate that the 6 service characters are mutually distinct; use ServiceStringAdvice::from_bytes_strict when that matters.

pub fn from_bytes_strict(input: &[u8]) -> Result<Self, EdifactError>

Parse a UNA header and validate that the four active service characters (element_sep, component_sep, release_char, segment_term) are all mutually distinct and are not ASCII whitespace (CR, LF, space, tab).

Returns EdifactError::InvalidUna if the invariant is violated. Falls back to ServiceStringAdvice::default when no UNA is present.

pub fn is_valid(&self) -> bool

Return true if the four active service characters are mutually distinct and none is ASCII whitespace (CR, LF, space, tab).

Trait Implementations

impl Clone for ServiceStringAdvice

fn clone(&self) -> ServiceStringAdvice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceStringAdvice

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

Formats the value using the given formatter.

impl Default for ServiceStringAdvice

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ServiceStringAdvice

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