default = ssl

The ssl feature is set by default whenever curl-sys is added without default-features = false somewhere in the dependency tree.

Enables vendored of openssl-sys

zlib-ng-compat = static-curl

Enables zlib-ng of libz-sys

libz-sys:

(Omit the libc feature if you don't require the corresponding functions.)

This allows higher-level crates depending on your library to opt into zlib-ng if desired.

Affects curl-sys::curl_easy_upkeep…

poll_7_68_0

Affects curl-sys::curl_multi_poll, curl-sys::curl_multi_wakeup…

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
