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.
