Struct opcua_server::prelude::ByteString

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

A sequence of octets.

Fields

value: Option<Vec<u8, Global>>

Implementations

impl ByteString

pub fn null() -> ByteString

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

pub fn is_null(&self) -> bool

Test if the string is null

pub fn is_empty(&self) -> bool

pub fn is_null_or_empty(&self) -> bool

Test if the string is null or empty

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

Creates a byte string from a Base64 encoded string

pub fn as_base64(&self) -> String

Encodes the bytestring as a Base64 encoded string

pub fn substring(&self, min: usize, max: usize) -> Result<ByteString, ()>

This function is meant for use with NumericRange. It creates a substring from this string from min up to and inclusive of max. Note that min must have an index within the string but max is allowed to be beyond the end in which case the remainder of the string is returned (see docs for NumericRange).

Trait Implementations

impl AsRef<[u8]> for ByteString

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

Performs the conversion.

impl BinaryEncoder<ByteString> for ByteString

pub fn byte_len(&self) -> usize

Returns the exact byte length of the structure as it would be if encode were called. This may be called prior to writing to ensure the correct amount of space is available.

pub fn encode<S>(&self, stream: &mut S) -> Result<usize, StatusCode> where
    S: Write, 

Encodes the instance to the write stream.

pub fn decode<S>(
    stream: &mut S,
    decoding_limits: &DecodingLimits
) -> Result<ByteString, StatusCode> where
    S: Read, 

Decodes an instance from the read stream. The decoding limits are restrictions set by the server / client on the length of strings, arrays etc. If these limits are exceeded the implementation should return with a BadDecodingError as soon as possible.

fn encode_to_vec(&self) -> Vec<u8, Global>

impl Clone for ByteString

pub fn clone(&self) -> ByteString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ByteString

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

Formats the value using the given formatter.

impl Default for ByteString

pub fn default() -> ByteString

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ByteString

pub fn deserialize<__D>(
    __deserializer: __D
) -> Result<ByteString, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

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

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

Performs the conversion.

impl From<ByteString> for Variant

pub fn from(v: ByteString) -> Variant

Performs the conversion.

impl From<ByteString> for DataValue

pub fn from(v: ByteString) -> DataValue

Performs the conversion.

impl From<ByteString> for Identifier

pub fn from(v: ByteString) -> Identifier

Performs the conversion.

impl From<Guid> for ByteString

pub fn from(value: Guid) -> ByteString

Performs the conversion.

impl From<Vec<u8, Global>> for ByteString

pub fn from(value: Vec<u8, Global>) -> ByteString

Performs the conversion.

impl Hash for ByteString

pub fn hash<__H>(&self, state: &mut __H) where
    __H: Hasher, 

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 Into<ByteString> for Thumbprint

pub fn into(self) -> ByteString

Performs the conversion.

impl Into<String> for ByteString

pub fn into(self) -> String

Performs the conversion.

impl PartialEq<ByteString> for ByteString

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

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

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

This method tests for !=.

impl Serialize for ByteString

pub fn serialize<__S>(
    &self,
    __serializer: __S
) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl<'_> TryFrom<&'_ ByteString> for Guid

type Error = ()

The type returned in the event of a conversion error.

pub fn try_from(
    value: &ByteString
) -> Result<Guid, <Guid as TryFrom<&'_ ByteString>>::Error>

Performs the conversion.
