Struct mail_headers::HeaderName

pub struct HeaderName { /* fields omitted */ }

Note: Normally you will never have the need to create a HeaderName instance by yourself (except maybe for testing). At last as long as you use def_header! for defining custom Headers, which is highly recommended

Methods

impl HeaderName

pub fn new(name: &'static SoftAsciiStr) -> Result<Self, InvalidHeaderName>

Be aware, that this library only accepts header names with a letter case, that any first character of an alphanumeric part of a header name has to be uppercase and all other lowercase. E.g. Message-Id is accepted but Message-ID is rejected, even through both are semantically the same. This frees us from doing either case insensitive comparison/hash wrt. hash map lookups, or converting all names to upper/lower case.

pub fn from_ascii_unchecked<B: ?Sized>(name: &'static B) -> HeaderName where
    B: AsRef<str>, 

pub fn as_ascii_str(&self) -> &'static SoftAsciiStr

pub fn as_str(&self) -> &'static str
