Struct HeaderPredicate 

pub struct HeaderPredicate {
    pub name: String,
    pub kind: i32,
    pub value: Option<String>,
}

A routing condition on one request header (sozu-proxy/sozu#1253).

name is matched case-insensitively per RFC 9110 §5.1 against the FIRST occurrence of the header in the request. It must be an RFC 9110 token and can be neither Host (the request authority, not a header Sōzu keeps) nor Cookie (parsed into a jar). A request that does not carry the header fails every kind of predicate.

Fields

name: String

kind: i32

value: Option<String>

Required for EXACT and REGEX, forbidden for PRESENT.

Implementations

impl HeaderPredicate

pub fn kind(&self) -> HeaderMatchKind

Returns the enum value of kind, or the default if the field is set to an invalid enum value.

pub fn set_kind(&mut self, value: HeaderMatchKind)

Sets kind to the provided enum value.

pub fn value(&self) -> &str

Returns the value of value, or the default value if value is unset.
