Struct HeaderLine

struct HeaderLine<'ln> {
    line_number: usize,
    original_line: &'ln str,
    header_revision: Option<&'ln str>,
    directive: &'ln str,
}

The broken-down contents of a line containing a test header directive, which iter_header passes to its callback function.

For example:

//@ compile-flags: -O
    ^^^^^^^^^^^^^^^^^ directive
^^^^^^^^^^^^^^^^^^^^^ original_line

//@ [foo] compile-flags: -O
     ^^^                    header_revision
          ^^^^^^^^^^^^^^^^^ directive
^^^^^^^^^^^^^^^^^^^^^^^^^^^ original_line

Fields

line_number: usize

original_line: &'ln str

Raw line from the test file, including comment prefix and any revision.

header_revision: Option<&'ln str>

Some header directives start with a revision name in square brackets (e.g. [foo]), and only apply to that revision of the test. If present, this field contains the revision name (e.g. foo).

directive: &'ln str

The main part of the header directive, after removing the comment prefix and the optional revision specifier.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
