Type Alias DerObjectContent 

pub type DerObjectContent<'a> = BerObjectContent<'a>;

BER object content

This is the same object as BerObjectContent.

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
