When trying to write or interpret cfg
statements like e.g.
#[cfg(all(unix, not(target_arch = "wasm32")))]
from the atty
crate,
I am sometimes unsure what exactly unix
means here. (Apparently it includes wasm
?)
Is there a full list of what rust compiler targets are in what target-family?
The cfg doc in the rust reference does not seem to have one.
Rust nightly now has --print all-target-specs-json
,
which has this information.
On rustc 1.72.0-nightly (8c74a5d27 2023-06-14)
,
I was able to gather the following output using
rustc +nightly -Z unstable-options --print all-target-specs-json | jq '[ to_entries[] | { "target": .key, "arch": .value.arch, "os": .value.os, "target-family": .value."target-family" } ]'
