Struct Header 

#[non_exhaustive]
pub struct Header {
    pub key: String,
    pub value: String,
    /* private fields */
}

Defines a header message. A header can have a key and a value.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: String

The Key of the header.

value: String

The Value of the header.

Implementations

impl Header

pub fn new() -> Self

Creates a new default instance.

pub fn set_key<T: Into<String>>(self, v: T) -> Self

Sets the value of key.

Example

let x = Header::new().set_key("example");

pub fn set_value<T: Into<String>>(self, v: T) -> Self

Sets the value of value.

Example

let x = Header::new().set_value("example");
