J W created THRIFT-4662: --------------------------- Summary: Rust const string calls function at compile time Key: THRIFT-4662 URL: https://issues.apache.org/jira/browse/THRIFT-4662 Project: Thrift Issue Type: Bug Components: Rust - Compiler Affects Versions: 0.11.0 Environment: C:\Users\jake>rustup show Default host: x86_64-pc-windows-msvc
stable-x86_64-pc-windows-msvc (default) rustc 1.30.0 (da5f414c2 2018-10-24) Reporter: J W *For this thrift:* const string broker_playback_message = "mmi.developer.playback" *Generates:* // thrift -gen rs -out ../rust/thrift/src const_string.thrift pub const BROKER_PLAYBACK_MESSAGE: String = "mmi.developer.playback".to_owned(); *Fails to compile:* error[E0015]: calls in constants are limited to tuple structs and tuple variants note: a limited form of compile-time function evaluation is available on a nightly compiler via `const fn` *Fix:* Probably want to output: pub const BROKER_PLAYBACK_MESSAGE: &str = "mmi.developer.playback"; Looking at render_const_value() it looks like byte arrays will have the same issue. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
