pub struct Cors { /* private fields */ }
Expand description

Response generator and Fairing for CORS

This struct can be as Fairing or in an ad-hoc manner to generate CORS response. See the documentation at the crate root for usage information.

This struct can be created by using CorsOptions::to_cors or Cors::from_options.

Implementations§

source§

impl Cors

source

pub fn from_options(options: &CorsOptions) -> Result<Self, Error>

Create a Cors struct from a CorsOptions

source

pub fn respond_owned<'r, 'o: 'r, F, R>( self, handler: F ) -> Result<ManualResponder<'r, F, R>, Error>where F: FnOnce(Guard<'r>) -> R + 'r, R: Responder<'r, 'o>,

Manually respond to a request with CORS checks and headers using an Owned Cors.

Use this variant when your Cors struct will not live at least as long as the whole 'r lifetime of the request.

After the CORS checks are done, the passed in handler closure will be run to generate a final response. You will have to merge your response with the Guard that you have been passed in to include the CORS headers.

See the documentation at the crate root for usage information.

source

pub fn respond_borrowed<'r, 'o: 'r, F, R>( &'r self, handler: F ) -> Result<ManualResponder<'r, F, R>, Error>where F: FnOnce(Guard<'r>) -> R + 'r, R: Responder<'r, 'o>,

Manually respond to a request with CORS checks and headers using a borrowed Cors.

Use this variant when your Cors struct will live at least as long as the whole 'r lifetime of the request. If you are getting your Cors from Rocket’s state, you will have to use the inner function to get a longer borrowed lifetime.

After the CORS checks are done, the passed in handler closure will be run to generate a final response. You will have to merge your response with the Guard that you have been passed in to include the CORS headers.

See the documentation at the crate root for usage information.

fn fg(&self, value: Color) -> Painted<&T>
