Struct ExtensionHeader 

pub struct ExtensionHeader<'a> { /* private fields */ }

Original scalar header facts, available before payload decoding/allocation.

A written DEFAULT FALSE has one readable field value. Its position is available before value parsing; trailing bytes are retained separately by ExtensionValue. Strict profiles refuse these facts, while inspection profiles can admit and retain diagnostics before decoding. No duplicate-extension or application recognition decision is made here.

Implementations

impl<'a> ExtensionHeader<'a>

pub fn kind(self) -> Oid<'a>

Original extnID, validated by the producing reader.

pub fn is_critical(self) -> bool

Written critical value, or the ASN.1 DEFAULT FALSE when absent.

pub fn critical_span(self) -> Option<Span>

Original complete BOOLEAN TLV span, absent when the flag was omitted.

pub fn span(self) -> Span

Original complete extension SEQUENCE span.

pub fn default_written(self) -> bool

A FALSE value was written explicitly (DER must omit it: X.690 §11.5).
