std brotli? read_buf?

Enables std of once_cell, rustls-pki-types, and rustls-webpki ^0.102.8

once_cell:

REQUIRED for no-std (with recent update to avoid any potential surprises with no atomic ptr support, etc.) NOTE: While it would be possible to use once_cell with critical-section feature, which would enable using once_cell::sync::OnceCell instead of once_cell::race::OnceBox, this does not seem to have so much benefit as the likelihood of multiple threads attempting to set the default crypto provider at the same time seems extremely low. Using once_cell::sync::OnceCell would let the losing thread to see the winning value in the error result from crypto::CryptoProvider::set_default(), which does not seem worth using the critical-section feature with its no-std installation requirements. TODO: specify once_cell version in single place - as RECENTLY UPDATED in upstream RUSTLS (It may be best to specify the once_cell features here, as may be needed for updates moving forward.)

Affects compress::CompressionCacheInner, ticketer::TicketRotator, time_provider::DefaultTimeProvider, portable-rustls::ticketer…

prefer-post-quantum = aws-lc-rs

read_buf = rustversion, std

ring

Enables ring, ring of rustls-webpki ^0.102.8

Affects crypto::ring…

tls12

Affects client_conn::ClientConfig.require_ems, crypto::tls12, server_conn::ServerConfig.require_ems, versions::TLS12…

zlib

Enables zlib-rs

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.

hashbrown implicit feature

Enables hashbrown

hashbrown:

A Rust port of Google's SwissTable hash map

Affects portable-rustls::ticketer…
