[−][src]Struct actix_request_identifier::RequestIdentifier
A middleware for generating per-request unique IDs
Implementations
impl RequestIdentifier
[src]
pub fn with_uuid() -> Self
[src]
Create a default middleware using DEFAULT_HEADER
as the header name and
UUID v4 for ID generation.
pub fn with_header(header_name: &'static str) -> Self
[src]
Create a middleware using a custom header name and UUID v4 for ID generation.
pub fn header(self, header_name: &'static str) -> Self
[src]
Change the header name for this middleware.
pub fn with_generator(id_generator: fn() -> HeaderValue) -> Self
[src]
Create a middleware using DEFAULT_HEADER
as the header
name and IDs as generated by id_generator
. id_generator
should return a unique ID
(ASCII only), each time it is invoked.
pub fn generator(self, id_generator: fn() -> HeaderValue) -> Self
[src]
Change the ID generator for this middleware.
