Struct opcua_types::byte_string::ByteString

pub struct ByteString {
    pub value: Option<Vec<u8>>,
}

A sequence of octets.

Fields

value: Option<Vec<u8>>

Methods

impl ByteString

fn null() -> ByteString

Create a null string (not the same as an empty string)

fn is_null(&self) -> bool

Test if the string is null

fn is_null_or_empty(&self) -> bool

Test if the string is null or empty

fn from_base64(data: &str) -> Option<ByteString>

Creates a byte string from a Base64 encoded string

fn as_base64(&self) -> String

Encodes the bytestring as a Base64 encoded string

fn nonce() -> ByteString

Creates a nonce - 32 bytes of random data

fn random(number_of_bytes: usize) -> ByteString

Create a byte string with a number of random characters. Can be used to create a nonce or a similar reason.

Trait Implementations

impl Eq for ByteString

impl PartialEq for ByteString

fn eq(&self, __arg_0: &ByteString) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &ByteString) -> bool

This method tests for !=.

impl Debug for ByteString

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for ByteString

fn clone(&self) -> ByteString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for ByteString

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

impl AsRef<[u8]> for ByteString

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl BinaryEncoder<ByteString> for ByteString

fn byte_len(&self) -> usize

Returns the byte length of the structure. This calculation should be exact and as efficient as possible.

fn encode<S: Write>(&self, stream: &mut S) -> EncodingResult<usize>

Encodes the instance to the write stream.

fn decode<S: Read>(stream: &mut S) -> EncodingResult<Self>

Decodes an instance from the read stream.

impl<'a, T: ?Sized> From<&'a T> for ByteString where
    T: AsRef<[u8]>, 

fn from(value: &'a T) -> Self

Performs the conversion.

impl From<Vec<u8>> for ByteString

fn from(value: Vec<u8>) -> Self

Performs the conversion.

impl Into<String> for ByteString

fn into(self) -> String

Performs the conversion.

impl Default for ByteString

fn default() -> Self

Returns the "default value" for a type.
