Error type for IdAllocator usage.

Variants

Overflow

Management operations on desired resource resulted in overflow.

OutOfRange(u32)

An id that is not part of the specified range was requested to be released.

AlreadyReleased(u32)

An id that was already released was requested to be released.

NeverAllocated(u32)

An id that was never allocated was requested to be released.

ResourceNotAvailable

The resource we want to use or update is not available.

InvalidRange(u64, u64)

The range to manage is invalid.

InvalidAlignment

Alignment value is invalid

Overlap(RangeInclusive, RangeInclusive)

The range that we try to insert into the interval tree is overlapping with another node from the tree.

InvalidStateTransition(RangeInclusive, NodeState)

A node state can be changed just from Free to Allocated, other transitions are not valid.

UnalignedAddress

Address is unaligned

Underflow

Management operations on desired resource resulted in underflow.

InvalidSize(u64)

The size of the desired resource is not invalid.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Ord for Error

fn cmp(&self, other: &Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Error> for Error

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

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

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

This method tests for !=.

impl PartialOrd<Error> for Error

fn partial_cmp(&self, other: &Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
