BER object content

Variants

EndOfContent

EOC (no content)

Boolean(bool)

BOOLEAN: decoded value

Integer(&'a [u8])

INTEGER: raw bytes

Note: the reason to store the raw bytes is that integers have non-finite length in the spec, and also that the raw encoding is also important for some applications.

To extract the number, see the as_u64, as_u32, as_bigint and as_biguint methods.

BitString(u8, BitStringObject<'a>)

BIT STRING: number of unused bits, and object

OctetString(&'a [u8])

OCTET STRING: slice

Null

NULL (no content)

Enum(u64)

ENUMERATED: decoded enum number

OID(Oid<'a>)

OID

RelativeOID(Oid<'a>)

RELATIVE OID

NumericString(&'a str)

NumericString: decoded string

VisibleString(&'a str)

VisibleString: decoded string

PrintableString(&'a str)

PrintableString: decoded string

IA5String(&'a str)

IA5String: decoded string

UTF8String(&'a str)

UTF8String: decoded string

T61String(&'a str)

T61String: decoded string

VideotexString(&'a str)

VideotexString: decoded string

BmpString(&'a str)

BmpString: decoded string

UniversalString(&'a [u8])

UniversalString: raw object bytes

Sequence(Vec<BerObject<'a>>)

SEQUENCE: list of objects

Set(Vec<BerObject<'a>>)

SET: list of objects

UTCTime(ASN1DateTime)

UTCTime: decoded string

GeneralizedTime(ASN1DateTime)

GeneralizedTime: decoded string

ObjectDescriptor(&'a str)

Object descriptor: decoded string

GraphicString(&'a str)

GraphicString: decoded string

GeneralString(&'a str)

GeneralString: decoded string

Optional(Option<Box<BerObject<'a>>>)

Optional object

Tagged(Class, Tag, Box<BerObject<'a>>)

Tagged object (EXPLICIT): class, tag and content of inner object

Unknown(Any<'a>)

Private or Unknown (for ex. unknown tag) object

Implementations

impl<'a> BerObjectContent<'a>

pub fn as_i64(&self) -> Result<i64, Error>

Attempt to read a signed integer value from this object.

This can fail if the object is not an integer, or if it is too large.

Examples

let der_int  = BerObject::from_int_slice(b"\x80");
assert_eq!(
    der_int.as_i64(),
    Ok(-128)
);

pub fn as_i32(&self) -> Result<i32, Error>

Attempt to read a signed integer value from this object.

This can fail if the object is not an integer, or if it is too large.

Examples

let der_int  = BerObject::from_int_slice(b"\x80");
assert_eq!(
    der_int.as_i32(),
    Ok(-128)
);

pub fn as_u64(&self) -> Result<u64, Error>

Attempt to read integer value from this object.

This can fail if the object is not an unsigned integer, or if it is too large.

Examples

let der_int  = BerObject::from_int_slice(b"\x01\x00\x01");
assert_eq!(
    der_int.as_u64(),
    Ok(0x10001)
);

pub fn as_u32(&self) -> Result<u32, Error>

Attempt to read integer value from this object.

This can fail if the object is not an unsigned integer, or if it is too large.

Examples

let der_int  = BerObject::from_obj(BerObjectContent::Integer(b"\x01\x00\x01"));
assert_eq!(
    der_int.as_u32(),
    Ok(0x10001)
);

pub fn as_bool(&self) -> Result<bool, Error>

pub fn as_oid(&self) -> Result<&Oid<'a>, Error>

pub fn as_oid_val(&self) -> Result<Oid<'a>, Error>

pub fn as_optional(&self) -> Result<Option<&BerObject<'a>>, Error>

pub fn as_tagged(&self) -> Result<(Class, Tag, &BerObject<'a>), Error>

pub fn as_bitstring_ref(&self) -> Result<&BitStringObject<'_>, Error>

pub fn as_bitstring(&self) -> Result<BitStringObject<'a>, Error>

pub fn as_sequence(&self) -> Result<&Vec<BerObject<'a>>, Error>

pub fn as_set(&self) -> Result<&Vec<BerObject<'a>>, Error>

pub fn as_slice(&self) -> Result<&'a [u8], Error>

pub fn as_str(&self) -> Result<&'a str, Error>

Trait Implementations

impl<'a> Clone for BerObjectContent<'a>

fn clone(&self) -> BerObjectContent<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for BerObjectContent<'a>

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

Formats the value using the given formatter.

impl<'a> From<BerObjectContent<'a>> for BerObject<'a>

Build a DER object from a BerObjectContent.

fn from(obj: BerObjectContent<'a>) -> BerObject<'a>

Converts to this type from the input type.

impl<'a> PartialEq for BerObjectContent<'a>

fn eq(&self, other: &BerObjectContent<'a>) -> 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.
