Struct VaryRule 

pub struct VaryRule { /* private fields */ }

A rule for variance of a request.

This rule describes what fields (headers) are used to determine whether a new request “matches” a previous response.

VaryRule is canonicalized, with lowercase-named header names in sorted order.

Implementations

impl VaryRule

pub fn new<'a>(headers: impl IntoIterator<Item = &'a HeaderName>) -> VaryRule

pub fn variant(&self, headers: &HeaderMap) -> Variant

Construct the Variant for the given headers: the (header, value) pairs that must be present for a request to match a response.

Trait Implementations

impl Clone for VaryRule

fn clone(&self) -> VaryRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VaryRule

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

Formats the value using the given formatter.

impl Default for VaryRule

fn default() -> VaryRule

Returns the “default value” for a type.

impl FromStr for VaryRule

type Err = Error

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 PartialEq for VaryRule

fn eq(&self, other: &VaryRule) -> 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.
