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 [u8])

BmpString: raw object bytes

Note: the string is stored as raw bytes because not all UTF-16 sequences can be stored as &str. To access content, use String::from_utf16 or String::from_utf16_lossy.

§

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)
