Enum tokio_fastcgi::Role

pub enum Role {
    Responder,
    Authorizer,
    Filter,
}

Enum containing the role that is requested from the FastCGI client. See the different variants for a description of the roles and their input and output streams.

Variants

Responder

A FastCGI responder receives all the information associated with an HTTP request and generates an HTTP response. A responder receives the following information from the web-server:

• Environment variables (see get_param/get_str_param)
• StdIn (see get_stdin)

A responder has the following communication channels at its disposal:

• Result code (see RequestResult)
• StdOut (see get_stdout)
• StdErr (see get_stderr)

see the FastCGI specification for more Information

Authorizer

A FastCGI authorizer receives all the information associated with an HTTP request and generates an authorized/unauthorized decision. In case of an authorized decision the authorizer can also associate name-value pairs with the HTTP request. A responder receives the following information from the web-server:

• Environment variables and request parameters (see get_param/get_str_param)

An authorizer has the following communication channels at its disposal:

• Result code (see RequestResult)
• StdOut (see get_stdout)
• StdErr (see get_stderr)

see the FastCGI specification for more Information

Filter

A FastCGI filter receives all the information associated with an HTTP request, plus an extra stream of data from a file stored on the Web server, and generates a “filtered” version of the data stream as an HTTP response. A filter receives the following information from the web-server:

• Environment variables, request parameters and additional information (FCGI_DATA_LAST_MOD and FCGI_DATA_LENGTH) (see get_param/get_str_param)
• StdIn (see get_stdin)
• File Data from the web-server (see get_data)

A filter has the following communication channels at its disposal:

• Result code (see RequestResult)
• StdOut (see get_stdout)
• StdErr (see get_stderr)

Trait Implementations

impl Debug for Role

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

Formats the value using the given formatter.

impl PartialEq for Role

fn eq(&self, other: &Role) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
