Enum Cause 

#[repr(u8)]
pub enum Cause {
    Unknown = 0,
    OutOfMemory = 1,
}

The cause of an error.

Variants

Unknown = 0

The cause is unknown.

This most commonly means an OSErr occurred, but os_err_reporting is disabled.

OutOfMemory = 1

The allocator ran out of memory.

This should only be used when the allocator runs out of memory and doesn’t grow. Use OSErr if the system runs out of memory.

Trait Implementations

impl Clone for Cause

fn clone(&self) -> Cause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cause

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

Formats the value using the given formatter.

impl Display for Cause

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

Formats the value using the given formatter.

impl PartialEq for Cause

fn eq(&self, other: &Cause) -> 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.

impl Copy for Cause

impl Eq for Cause

impl StructuralPartialEq for Cause
