Struct DirectoryValidator 

pub struct DirectoryValidator { /* private fields */ }

Shared validator implementation that is configured per UN/EDIFACT directory release.

Scope and limitations

DirectoryValidator validates individual segment content (element counts, component counts, code-list values, and conditional rules) and checks that every mandatory segment type is present at least once. It does not validate segment sequence or repetition cardinality — i.e., it cannot tell you that a BGM segment appears more than once, or that a RFF group appears in the wrong position. Full sequence validation requires a state-machine per message type (UN/EDIFACT Segment Tables) which is outside the scope of this implementation.

Implementations

impl DirectoryValidator

pub fn new( directory_id: &'static str, segment_lookup: fn(&str) -> Option<&'static SegmentDefinition>, is_code_valid: fn(&str, &str) -> bool, suggest_code: fn(&str, &str) -> Option<&'static str>, expected_components: fn(&str, usize) -> Option<u8>, additional_structure_rule: Option<fn(&Segment<'_>) -> Result<(), EdifactError>>, ) -> Self

Create a validator for a specific directory release with injected lookup/check hooks.

pub fn with_code_list_rules( self, f: fn(tag: &str) -> &'static [(usize, usize, &'static str)], ) -> Self

Override the code-list rules function.

Directories can supply a directory-specific implementation that extends or replaces the base rules from base_code_list_rules.

pub fn structure_only(self) -> Self

Enable only structure checks and disable code-list checks.

pub fn code_list_only(self) -> Self

Enable only code-list checks and disable structure checks.

pub fn enforce_known_tags(self, enforce: bool) -> Self

Configure whether unknown segment tags should be rejected.

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

Performs copy-assignment from source.

impl Debug for DirectoryValidator

impl Validator for DirectoryValidator

fn set_message_type(&mut self, message_type: Option<&str>)

Configure message-type metadata for validators that support explicit scoping.

fn validate_batch( &self, segments: &[Segment<'_>], report: &mut ValidationReport, )

Validate a full segment set and append issues to report.
