impl Clone for TryReserveError

pub fn clone(&self) -> TryReserveError

返回值的副本。

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

从 source 执行复制分配。

impl Debug for TryReserveError

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 TryReserveError

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

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
