Enum LayoutErr 

#[repr(u8)]
pub enum LayoutErr {
    ZeroAlign = 0,
    NonPowerOfTwoAlign = 1,
    Overflow = 2,
}

An error that can occur when computing a layout.

Variants

ZeroAlign = 0

The alignment is zero.

NonPowerOfTwoAlign = 1

The alignment is not a power of two.

Overflow = 2

The requested size was greater than USIZE_MAX_NO_HIGH_BIT when rounded up to the nearest multiple of the requested alignment.

Trait Implementations

impl Clone for LayoutErr

fn clone(&self) -> LayoutErr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutErr

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

Formats the value using the given formatter.

impl Display for LayoutErr

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

Formats the value using the given formatter.

impl Error for LayoutErr

Available on crate feature std only.

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for LayoutErr

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