#[non_exhaustive]
pub enum BacktraceStyle { Short, Full, Off, }
🔬This is a nightly-only experimental API. (panic_backtrace_config #93346)
Expand description

默认 panic 钩子,是否以及如何捕获和显示回溯的配置。

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Short

🔬This is a nightly-only experimental API. (panic_backtrace_config #93346)

打印一个简洁的回溯,理想情况下只包含相关信息。

§

Full

🔬This is a nightly-only experimental API. (panic_backtrace_config #93346)

打印包含所有可能信息的回溯。

§

Off

🔬This is a nightly-only experimental API. (panic_backtrace_config #93346)

禁用收集和显示回溯。
