构建 trpl-ebook 时遇到错误:没有主体的方法中不允许使用模式
Error encountered while building trpl-ebook: patterns aren't allowed in methods without bodies
我想为我的 Kindle 生成 The Rust Programming Language 的 epub 电子书。
我下载了this Github project重建本书第二版草稿。当我执行 cargo run --release
时,遇到以下错误:

我试图搜索和调试错误,但由于我目前对 Rust 缺乏了解而无法这样做。还有其他人遇到过这个错误吗?
我正在使用 Ubuntu 16.04,Rust 1.25.0-nightly (b5392f545 2018-01-08),xargo 0.3.10,cargo 0.25.0-nightly (a88fbace4 2017-12-29)
rustc-serialize 0.3.19 于 2016 年 4 月 4 日发布。它包括语法:
fn read_enum_struct_variant_field<T, F>(
&mut self,
&f_name: &str, // This is no longer allowed
f_idx: usize,
f: F,
) -> Result<T, Self::Error>;
此语法在 Oct 21, 2016 (Rust 1.14.0) when it was turned into a warning. On Nov 4, 2017 (Rust 1.23.0) 之前被错误地允许,这变成了一个错误。
解决方法是更新rustc-serialize的版本:
cargo update -p rustc-serialize
