Struct HeaderValue

pub struct HeaderValue { /* private fields */ }

A struct representing value of a given header. Can contain one or more elements.

Examples

use std::str::FromStr;
let mut headers = async_nats::HeaderMap::new();
headers.insert("Key", "Value");
headers.insert("Another", async_nats::HeaderValue::from_str("AnotherValue")?);

Implementations

impl HeaderValue

pub fn new() -> HeaderValue

pub fn iter(&self) -> Iter<'_, String>

pub fn as_str(&self) -> &str

Trait Implementations

impl Clone for HeaderValue

fn clone(&self) -> HeaderValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderValue

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

Formats the value using the given formatter.

impl Default for HeaderValue

fn default() -> HeaderValue

Returns the “default value” for a type.

impl<'a> From<&'a HeaderValue> for &'a str

fn from(header: &'a HeaderValue) -> Self

Converts to this type from the input type.

impl From<&HeaderValue> for String

fn from(header: &HeaderValue) -> Self

Converts to this type from the input type.

impl From<&str> for HeaderValue

fn from(v: &str) -> Self

Converts to this type from the input type.

impl From<HeaderValue> for String

fn from(header: HeaderValue) -> Self

Converts to this type from the input type.

impl From<u64> for HeaderValue

fn from(v: u64) -> Self

Converts to this type from the input type.

impl FromStr for HeaderValue

type Err = ParseError

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 IntoHeaderValue for HeaderValue

fn into_header_value(self) -> HeaderValue

impl IntoIterator for HeaderValue

type Item = String

The type of the elements being iterated over.

type IntoIter = IntoIter<String>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for HeaderValue

fn eq(&self, other: &HeaderValue) -> 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 Serialize for HeaderValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToString for HeaderValue

fn to_string(&self) -> String

Converts the given value to a String.

impl Eq for HeaderValue

impl StructuralPartialEq for HeaderValue
