[−][src]Macro async_coap_uri::uri

macro_rules! uri {
    ( unsafe $S:expr ) => { ... };
    ( $S:expr ) => { ... };
    ( ) => { ... };
}

Creates a &'static Uri from a string literal.

Accepts only string constants and literals. The given string MUST be well-formed.

Example:

let x = uri!("http://example.com");
assert_eq!(x.scheme(),Some("http"));
assert_eq!(x.raw_authority(),Some("example.com"));

Checks for correctness are performed at compile time:

ⓘThis example deliberately fails to compile
// This will not compile.
let x = uri!("%00 invalid %ff");

Passing something that is a valid URI-Reference but not a valid URI (i.e.: Missing scheme) will also not compile:

ⓘThis example deliberately fails to compile
// This will not compile because "a/b/c" isn't a valid URI.
let x = uri!("a/b/c");
