Struct SyntaxValidator 

pub struct SyntaxValidator;

Checks the ISO 9735-1 rules that hold for every interchange, whatever directory or profile it claims.

These are the rules a partner’s translator enforces before it ever looks at a message type, and they need no directory to check:

Rule	Source	Reported as
A segment carries at least one data element besides its tag	§7.5, §8.5	E046
No data element value is made only of spaces	§9.3	E045 (warning)

Both are things a hand-rolled writer produces by accident: an ABC' where a conditional segment should have been dropped entirely, or a fixed-width field padded with spaces instead of suppressed. Neither trips a count check, and both are rejected downstream.

Registered by ValidationContextBuilder::with_syntax_validation.

Example

use edifact_rs::{from_bytes, ValidationContext};

// `FTX+` carries a value of nothing but spaces; `DTM` carries no data at all.
let segments: Vec<_> = from_bytes(b"FTX+   'DTM'")
    .collect::<Result<_, _>>()?;

let report = ValidationContext::builder()
    .with_syntax_validation()
    .build()
    .validate_lenient(&segments);

assert_eq!(report.errors()[0].error_code(), Some("E046")); // DTM has no data element
assert_eq!(report.warnings()[0].error_code(), Some("E045")); // FTX value is only spaces

Trait Implementations

impl Validator for SyntaxValidator

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

Validate a full segment set and append issues to report.

fn fork(&self) -> Option<Box<dyn Validator + Send + Sync>>

Create a Box<dyn Validator> clone of this validator for context forking.

fn validate_group_batch( &self, _root: &SegmentGroupIndexed<'_>, _all_segments: &[Segment<'_>], _report: &mut ValidationReport, _context: &ValidationRuleContext<'_>, )

Validate a segment-group tree and append issues to report.

fn has_group_rules(&self) -> bool

Returns true if this validator has any group-scoped rules.

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

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