//! `aconfig_flags` is a crate for reading aconfig flags from Rust
// When building with the Android tool-chain
//
//   - the flag functions will read from aconfig_flags_inner
//   - the feature "cargo" will be disabled
//
// When building with cargo
//
//   - the flag functions will all return some trivial value, like true
//   - the feature "cargo" will be enabled
//
// This module hides these differences from the rest of aconfig.

/// Module used when building with the Android tool-chain
#[cfg(not(feature = "cargo"))]
