Struct http_types::headers::HeaderName

pub struct HeaderName(_);

A header name.

Implementations

impl HeaderName

pub fn from_bytes(bytes: Vec<u8>) -> Result<Self, Error>

Create a new HeaderName from a Vec of ASCII bytes.

Error

This function will error if the bytes is not valid ASCII.

pub fn from_string(s: String) -> Result<Self, Error>

Create a new HeaderName from an ASCII string.

Error

This function will error if the string is not valid ASCII.

pub fn as_str(&self) -> &str

Returns the header name as a &str.

pub unsafe fn from_bytes_unchecked(bytes: Vec<u8>) -> Self

Converts a vector of bytes to a HeaderName without checking that the string contains valid ASCII.

Safety

This function is unsafe because it does not check that the bytes passed to it are valid ASCII. If this constraint is violated, it may cause memory unsafety issues with future users of the HeaderName, as the rest of the library assumes that Strings are valid ASCII.

Trait Implementations

impl Clone for HeaderName

fn clone(&self) -> HeaderName

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderName

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

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

fn from(value: &'a str) -> Self

impl<'a> PartialEq<&'a str> for HeaderName

fn eq(&self, other: &&'a str) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<HeaderName> for HeaderName

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<String> for HeaderName

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<str> for HeaderName

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

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

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