Struct Prefix

pub struct Prefix { /* private fields */ }

An Object ID Prefix designed to be similar to a human readable “subject line” for the OID

The prefix can store up to 8 bytes of 7-bit ASCII characters inline; a prefix of longer than 8 bytes will be “spilled” to the heap

Implementations

impl Prefix

pub fn from_slice(slice: &[u8]) -> Result<Self>

Create a Prefix from a slice of bytes. The bytes must be ASCII values of 0-9, A-Z, or a-z, additionally the byte slice length must be equal to the prefix length.

pub fn from_slice_unchecked(slice: &[u8]) -> Self

Create a Prefix from a slice of bytes without checking the length or validity of the bytes

Trait Implementations

impl Clone for Prefix

fn clone(&self) -> Prefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Prefix

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

Formats the value using the given formatter.

impl Display for Prefix

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

Formats the value using the given formatter.

impl FromStr for Prefix

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Prefix

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Prefix

fn eq(&self, other: &Prefix) -> 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.

impl TryFrom<&[u8]> for Prefix

type Error = Error

The type returned in the event of a conversion error.

fn try_from(slice: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for Prefix

type Error = Error

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.
