Enum std::panic::BacktraceStyle

#[non_exhaustive]
pub enum BacktraceStyle {
    Short,
    Full,
    Off,
}

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

默认 panic 钩子，是否以及如何捕获和显示回溯的配置。

Variants (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。

Trait Implementations

impl Clone for BacktraceStyle

fn clone(&self) -> BacktraceStyle

返回值的副本。

fn clone_from(&mut self, source: &Self)

从 source 执行复制分配。

impl Debug for BacktraceStyle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

使用给定的格式化程序格式化该值。

impl PartialEq<BacktraceStyle> for BacktraceStyle

fn eq(&self, other: &BacktraceStyle) -> bool

此方法测试 self 和 other 值是否相等，并由 == 使用。

fn ne(&self, other: &Rhs) -> bool

此方法测试 !=。 默认实现几乎总是足够的，并且不应在没有充分理由的情况下被覆盖。
