Struct Base128UInt

pub struct Base128UInt;

Combinator for a single identifier component in the OBJECT IDENTIFIER ASN.1 type (called “arc” X.690)

Basically an Arc is encoded as a “base-128” integer where the highest bit of every byte is set to 1 except for the last byte

e.g. 0b11111111 (0xff) => 0b1 * 128 + 0b01111111 => 0b10000001 0b011111111

NOTE: the first and second arcs of an OID are encoded differently

Trait Implementations

impl Combinator for Base128UInt

type Result<'a> = u64

The result type of parsing and the input type of serialization.

type Owned = u64

The owned parsed type. This is currently a hack to avoid lifetime bindings in SpecCombinator::SpecResult , but it can be useful if we want to have functions that return owned values (e.g. Vec<T>).

fn length(&self) -> Option<usize>

The length of the output buffer, if known. This can be used to optimize serialization by pre-allocating the buffer.

fn parse<'a>( &self, s: &'a [u8], ) -> Result<(usize, Self::Result<'a>), ParseError>

The parsing function.

fn serialize( &self, v: Self::Result<'_>, data: &mut Vec<u8>, pos: usize, ) -> Result<usize, SerializeError>

The serialization function.

impl Debug for Base128UInt

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

Formats the value using the given formatter.

impl SpecCombinator for Base128UInt

type SpecResult = u64

The view of Combinator::Result.
