Struct RouteMatch

pub struct RouteMatch {
    pub path: Option<PathMatch>,
    pub headers: Vec<HeaderMatch>,
    pub query_params: Vec<QueryParamMatch>,
    pub method: Option<Method>,
}

Defines the predicate used to match requests to a given action. Multiple match types are ANDed together; the match will evaluate to true only if all conditions are satisfied. For example, if a match specifies a path match and two query_params matches, it will match only if the request’s path matches and both of the query_params are matches.

The default RouteMatch functions like a path match on the empty prefix, which matches every request.

Match Ordering

Route matches are Ordered to help break ties. While once a Route is constructed, rules are matched in-order, sorting matches and rules can be useful while constructing a Route in case there isn’t an obvious order matches should apply in. From highest-value to lowest value, routes are ordered by:

• “Exact” path match.
• “Prefix” path match with largest number of characters.
• Method match.
• Largest number of header matches.
• Largest number of query param matches.

Note that this means a route that matches on a path is greater than a route that only matches on headers. To get a natural sort order by precedence, you may want to reverse-sort a list of matches.

Fields

path: Option<PathMatch>

Specifies a HTTP request path matcher.

headers: Vec<HeaderMatch>

Specifies HTTP request header matchers. Multiple match values are ANDed together, meaning, a request must match all the specified headers.

query_params: Vec<QueryParamMatch>

Specifies HTTP query parameter matchers. Multiple match values are ANDed together, meaning, a request must match all the specified query parameters.

method: Option<Method>

Specifies HTTP method matcher. When specified, this route will be matched only if the request has the specified method.

Implementations

impl RouteMatch

pub fn from_xds(r: &RouteMatch) -> Result<Self, Error>

Trait Implementations

impl Clone for RouteMatch

fn clone(&self) -> RouteMatch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RouteMatch

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

Formats the value using the given formatter.

impl Default for RouteMatch

fn default() -> RouteMatch

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RouteMatch

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for RouteMatch

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RouteMatch

fn eq(&self, other: &RouteMatch) -> 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 PartialOrd for RouteMatch

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for RouteMatch

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for RouteMatch
