Struct flurry::TryInsertError

pub struct TryInsertError<'a, V> {
    pub current: &'a V,
    pub not_inserted: V,
}

Fields

current: &'a V

A reference to the current value mapped to the key.

not_inserted: V

The value that HashMap::try_insert failed to insert.

Trait Implementations

impl<'a, V: Clone> Clone for TryInsertError<'a, V>

fn clone(&self) -> TryInsertError<'a, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, V: Copy> Copy for TryInsertError<'a, V>

impl<'a, V: Debug> Debug for TryInsertError<'a, V>

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

Formats the value using the given formatter.

impl<'a, V> Display for TryInsertError<'a, V> where
    V: Debug, 

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

Formats the value using the given formatter.

impl<'a, V: Eq> Eq for TryInsertError<'a, V>

impl<'a, V> Error for TryInsertError<'a, V> where
    V: Debug, 

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

The lower-level source of this error, if any.

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

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<'a, V: PartialEq> PartialEq<TryInsertError<'a, V>> for TryInsertError<'a, V>

fn eq(&self, other: &TryInsertError<'a, V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &TryInsertError<'a, V>) -> bool

This method tests for !=.
