Unable to compile on stable rust version

[TheAifam5]

Hey!

I am unable to use that package because of an issue in kvfilter. Is there any workaround for that?

Environment:
rustup 1.18.3 (2019-05-23)
rustc 1.37.0 (eae3437df 2019-08-13)

Related issue:
slog-rs/kvfilter#17

Regards,

Thank you for reporting this issue.

I tried to reproduce this problem, but I couldn't do it (i.e., the compilation was succeeded).
The following commands are the log:

$ uname -a
Linux foo 4.4.0-17763-Microsoft #379-Microsoft Wed Mar 06 19:16:00 PST 2019 x86_64 GNU/Linux

$ rustc --version
rustc 1.37.0 (eae3437df 2019-08-13)

$ git clone git@github.com:sile/sloggers.git
$ cd sloggers

Could you tell me more information about your environment?

That issue is related to this: slog-rs/kvfilter#17
while compiling with dynamic-keys feature.

I see. Thank you for your information.
I made slog-kvfilter an optional feature and added it to the default feature list of sloggers.
By using sloggers after v0.3.4, you can disable slog-kvfilter as follows:

# Cargo.toml
[package]
name = "slog-test"
version = "0.1.0"
edition = "2018"

[dependencies]
slog = {version="2", features=["dynamic-keys"]}
sloggers = {version="0.3", default-features=false}  # disable default features (i.e., slog-kvfilter)
