Struct std::alloc::AllocError

pub struct AllocError;

🔬 This is a nightly-only experimental API. (allocator_api #32838)

AllocError 错误表示分配失败，这可能是由于资源耗尽或将给定输入参数与此分配器组合在一起时出错所致。

Trait Implementations

impl Clone for AllocError

pub fn clone(&self) -> AllocError

返回值的副本。

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

从 source 执行复制分配。

impl Debug for AllocError

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

使用给定的格式化程序格式化该值。

impl Display for AllocError

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

使用给定的格式化程序格式化该值。

impl Error for AllocError

fn source(&self) -> Option<&(dyn Error + 'static)>

此错误的下级来源 (如果有)。

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace #53487)

返回发生错误的栈回溯 (如果有)。

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<AllocError> for AllocError

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

此方法测试 self 和 other 值是否相等，并由 == 使用。

#[must_use]

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

此方法测试 !=。
