-------------------------------------
> 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
> Assignee: Allen George
> Priority: Major
> Fix For: 0.12.0
>
>
> *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.
