[]Struct rocket::http::uri::Segments

pub struct Segments<'a>(pub &'a str);

Iterator over the segments of an absolute URI path. Skips empty segments.

Examples

use rocket::http::uri::Origin;

let uri = Origin::parse("/a/////b/c////////d").unwrap();
let segments = uri.segments();
for (i, segment) in segments.enumerate() {
    match i {
        0 => assert_eq!(segment, "a"),
        1 => assert_eq!(segment, "b"),
        2 => assert_eq!(segment, "c"),
        3 => assert_eq!(segment, "d"),
        _ => panic!("only four segments")
    }
}

Methods

impl<'a> Segments<'a>

Creates a PathBuf from a Segments iterator. The returned PathBuf is percent-decoded. If a segment is equal to "..", the previous segment (if any) is skipped.

For security purposes, if a segment meets any of the following conditions, an Err is returned indicating the condition met:

  • Decoded segment starts with any of: '*'
  • Decoded segment ends with any of: :, >, <
  • Decoded segment contains any of: /
  • On Windows, decoded segment contains any of: \
  • Percent-encoding results in invalid UTF8.

Additionally, if allow_dotfiles is false, an Err is returned if the following condition is met:

  • Decoded segment starts with any of: . (except ..)

As a result of these conditions, a PathBuf derived via FromSegments is safe to interpolate within, or use as a suffix of, a path without additional checks.
