Struct Asn1Value 

pub struct Asn1Value { /* private fields */ }

Owned DER value + builder. Constructs canonical X.690 DER programmatically for reference and testing. alloc-gated — the pipeline binds the borrowed Asn1Carrier handle, which needs no allocator. There is no width or element-count ceiling.

Implementations

impl Asn1Value

pub fn parse(raw: &[u8]) -> Result<Self, ShapeViolation>

Validate a DER byte sequence and retain an owned copy.

Errors

Surfaces the [ShapeViolation] validate_der would raise.

pub fn boolean(value: bool) -> Self

Build a Boolean (DER tag 0x01).

pub fn null() -> Self

Build a Null (DER tag 0x05).

pub fn integer(value: i64) -> Self

Build an Integer (DER tag 0x02) from a signed 64-bit value. DER §8.3: minimum-octets two’s-complement big-endian.

pub fn octet_string(bytes: &[u8]) -> Self

Build an OctetString (DER tag 0x04) from raw bytes.

pub fn sequence(children: &[Asn1Value]) -> Self

Build a Sequence (DER tag 0x30).

pub fn set(children: &[Asn1Value]) -> Self

Build a Set (DER tag 0x31). DER (X.690 §11.6) requires Set element ordering by ascending encoded-element byte sequence.

pub fn bit_string(bits: &[u8], unused_bits: u8) -> Result<Self, ShapeViolation>

Build a BIT STRING (DER tag 0x03). X.690 §8.6 / §11.2.

Errors

[INVALID_DER_VIOLATION] for invalid unused-bit counts or non-zero trailing bits.

pub fn object_identifier(arcs: &[u32]) -> Result<Self, ShapeViolation>

Build an OBJECT IDENTIFIER (DER tag 0x06). X.690 §8.19.

Errors

[INVALID_DER_VIOLATION] for fewer than two arcs or out-of-range leading arcs.

pub fn utf8_string(s: &str) -> Self

Build a UTF8String (DER tag 0x0C).

pub fn printable_string(s: &str) -> Result<Self, ShapeViolation>

Build a PrintableString (DER tag 0x13). X.680 §41.4 character set.

Errors

[INVALID_DER_VIOLATION] for characters outside the PrintableString set.

pub fn ia5_string(s: &str) -> Result<Self, ShapeViolation>

Build an IA5String (DER tag 0x16). X.680 §41.2.

Errors

[INVALID_DER_VIOLATION] for non-ASCII input.

pub fn tagged_bytes(&self) -> &[u8]

Borrow the DER-encoded canonical bytes.
