Enum StackError 

#[non_exhaustive]
pub enum StackError {
    Empty,
    CountOverflow,
    InvalidDamage,
    ConflictingDamage,
}

A stack operation could not represent the requested count.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

Empty stacks are represented by None, not by a zero-count item.

CountOverflow

Adding items would overflow the record’s count.

InvalidDamage

Damage must be a nonnegative integer representable by u32.

ConflictingDamage

A patch and the damage field (or a patch value and removal) disagree.

Trait Implementations

impl Clone for StackError

fn clone(&self) -> StackError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StackError

impl Debug for StackError

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

Formats the value using the given formatter.

impl Eq for StackError

impl Error for StackError

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 StackError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for StackError

impl Wire for StackError

const MIN: usize = 4usize

Minimum encoded size, used to reject impossible collection lengths.

fn put(&self, out: &mut Writer)

Encodes this value, recording failures on the writer.

fn put_owned(self, out: &mut Writer)

Consumes owned data when a resource’s ownership must cross the boundary.

fn take(input: &mut Reader<'_>) -> Result<StackError, WireError>

Decodes one value, leaving any following bytes for the caller.
