Enum CowGuardError 

pub enum CowGuardError {
    Poisoned,
    ExclusiveLockPending,
    WouldBlock,
}

A error for the Cow operations.

Variants

ExclusiveLockPending

An exclusive lock is pending so another writing opration performing Cow would block.

WouldBlock

Is returned by the borrow operation if an exclusive lock (non-cow op) is pending.

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

Formats the value using the given formatter.

impl Display for CowGuardError

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

impl PartialEq for CowGuardError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
