Expand description

Representation of a BER-encoded (X.690) object

A BER object is composed of a header describing the object class, type and length, and the content.

Note that the content may sometimes not match the header tag (for ex when parsing IMPLICIT tagged values).

Fields

header: BerObjectHeader<'a>content: BerObjectContent<'a>

Implementations

source

impl<'a> BerObject<'a>

source

pub fn from_header_and_content<'o>(
header: BerObjectHeader<'o>,
content: BerObjectContent<'o>
) -> BerObject<'o>

Build a BerObject from a header and content.

Note: values are not checked, so the tag can be different from the real content, or flags can be invalid.

source

pub fn from_obj(c: BerObjectContent<'_>) -> BerObject<'_>

Build a BerObject from its content, using default flags (no class, correct tag, and structured flag set only for Set and Sequence)

source

pub fn from_int_slice(i: &'a [u8 ]) -> BerObject<'a>

Build a DER integer object from a slice containing an encoded integer

source

pub fn set_raw_tag(self, raw_tag: Option<&'a [u8 ]>) -> BerObject<'_>

Set a tag for the BER object

source

pub fn from_seq(l: Vec<BerObject<'_>>) -> BerObject<'_>

Build a DER sequence object from a vector of DER objects

source

pub fn from_set(l: Vec<BerObject<'_>>) -> BerObject<'_>

Build a DER set object from a vector of DER objects

source

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

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

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

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

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

Attempt to read integer value from DER object.

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

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

Attempt to read integer value from DER object.

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

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

Attempt to read integer value from DER object. This can fail if the object is not a boolean.

source

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

Attempt to read an OID value from DER object. This can fail if the object is not an OID.

source

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

Attempt to read an OID value from DER object. This can fail if the object is not an OID.

source

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

Attempt to get a reference on the content from an optional object. This can fail if the object is not optional.

source

pub fn as_tagged(
&'a self
) -> Result<(BerClass, BerTag, &BerObject<'a>), BerError>

Attempt to get a reference on the content from a tagged object. This can fail if the object is not tagged.

source

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

Attempt to read a reference to a BitString value from DER object. This can fail if the object is not an BitString.

Note that this function returns a reference to the BitString. To get an owned value, use as_bitstring

source

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

Attempt to read a BitString value from DER object. This can fail if the object is not an BitString.

source

pub fn as_bitslice(&self) -> Result<&BitSlice<Msb0, u8>, BerError>

Constructs a shared &BitSlice reference over the object data, if available as slice.

source

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

source

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

Attempt to read an integer value from this object.

This can fail if the object is not an integer.

Examples

use der_parser::ber::*;

let data = &[0x02, 0x03, 0x01, 0x00, 0x01];

assert_eq!(object.as_bigint(), Ok(65537.into()))

source

pub fn as_biguint(&self) -> Result<BigUint, BerError>

This is supported on crate feature bigint only.

use der_parser::ber::*;

let data = &[0x02, 0x03, 0x01, 0x00, 0x01];

impl<'a> BerObject<'a>

source

pub fn ref_iter(&'a self) -> BerObjectRefIterator<'a>ⓘNotable traits for BerObjectRefIterator<'a>`impl<'a> Iterator for BerObjectRefIterator<'a> type Item = &'a BerObject<'a>;`

source

pub fn to_vec(&self) -> Result<Vec<u8>, GenError>

This is supported on crate feature serialize only.

Attempt to encode object as BER

Note that the encoding will not check that the values of the BerObject fields are correct. The length is automatically calculated, and the field is ignored.

Tagged objects will be encoded as EXPLICIT.

This function is only available if the serialize feature is enabled.
