//! `open_wire` must not depend on how the consumer's feature graph resolves a
|
||
|
|
//! rustls provider — it installs the process default itself, first.
|
||
|
|
//!
|
||
|
|
//! This is the belt-and-braces half of the fix for the on-device "Failed to
|
||
|
|
//! start / Could not automatically determine the process-level CryptoProvider"
|
||
|
|
//! screen; the primary fix is the `rustls` `ring` feature in `Cargo.toml`,
|
||
|
|
//! covered by `tests/provider_resolution.rs`. Kept in its own test binary on
|
||
|
|
//! purpose: installing a provider here would mask that test if they shared a
|
||
|
|
//! process.
