QUESTION
I would like to read a GRIB file downloaded from server using ecCodes library in Rust. However, my current solution results in segmentation fault. The extracted example, replicating the problem, is below.
I download the file using reqwest
crate and get the response as Bytes
1 using bytes()
. To read the file with ecCodes I need to create a codes_handle
using codes_grib_handle_new_from_file()
2, which as argument requires *FILE
usually get from fopen()
. However, I would like to skip IO operations. So I figured I could use libc::fmemopen()
to get *FILE
from Bytes
. But when I pass the *mut FILE
from fmemopen()
to codes_grib_handle_new_from_file()
segmentation fault occurs.
I suspect the issue is when I get from Bytes
a *mut c_void
required by fmemopen()
. I figured I can do this like that:

QUESTION
Can the Cross-Origin-Embedder-Policy
and Cross-Origin-Opener-Policy
headers be set with tags, or can they only be set with actual headers? If not, is there a list of headers which can be set with meta tags?
The following example logs crossOriginIsolated: false
to the console.
ANSWER
Answered 2021-May-20 at 08:17No, they can't.
According to this spec, http-equiv
supports only a few HTTP headers.
https://html.spec.whatwg.org/multipage/semantics.html#attr-meta-http-equiv.
That means these headers can be set only as HTTP ("actual") headers by a server.
Supporting them in HTML would be a security bug.

this problem has got me almost depressed..
not so long ago this whole app worked but recently (probably more than 3 months, perhaps 6) one of my routes refuses to render any handlebars template I pass it, including ones that are rendering successfully via other routes.
this is the offending route:
...ANSWER
Answered 2021-Jan-22 at 12:08After starting a brand new project and pulling this one route in I had a moment of enlightenment - here's the answer for anybody who hits a similar problem:
I was using the express-handlebars package which defaulted to main.hbs as it's layout.
I'd written a bunch of conditionals in there (bit of a noob error on reflection) which was preventing the body ever rendering - must've been a bit of a fluke that only this route was broken.
Lesson: don't put any complicated logic in your main.hbs file if your using express-handlebars.
