Struct ScopeStackVariable

pub struct ScopeStackVariable(/* private fields */);

Represents an unknown list of exported scopes.

Implementations

impl ScopeStackVariable

pub fn new(variable: u32) -> Option<ScopeStackVariable>

pub fn with_offset(self, scope_variable_offset: u32) -> ScopeStackVariable

Applies an offset to this variable.

When concatenating partial paths, we have to ensure that the left- and right-hand sides have non-overlapping sets of variables. To do this, we find the maximum value of any variable on the left-hand side, and add this “offset” to the values of all of the variables on the right-hand side.

Trait Implementations

impl Clone for ScopeStackVariable

fn clone(&self) -> ScopeStackVariable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScopeStackVariable

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

Formats the value using the given formatter.

impl Display for ScopeStackVariable

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

Formats the value using the given formatter.

impl From<NonZero<u32>> for ScopeStackVariable

fn from(value: NonZeroU32) -> ScopeStackVariable

Converts to this type from the input type.

impl Hash for ScopeStackVariable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Into<u32> for ScopeStackVariable

fn into(self) -> u32

Converts this type into the (usually inferred) input type.

impl Niche for ScopeStackVariable

where NonZeroU32: Niche,

type Output = MaybeUninit<ScopeStackVariable>

The type that is used to store values of Self inside of a ControlledOption. This might be Self itself, if your niche is a valid instance of the type, but which violates some runtime constraint. But if you cannot easily create your niche as an instance of Self, you can use some other type, you can use some other type instead.

fn none() -> Self::Output

Returns the niche value for this type that should be used to represent None for a ControlledOption.

fn is_none(value: &Self::Output) -> bool

Returns whether value is the niche value for this type.

fn into_some(value: Self) -> Self::Output

Transforms a non-niche value of this type into its Output type. When Output is Self, this will be the identity function.

fn from_some(value: Self::Output) -> Self

Transforms a non-niche value of this type from its Output type. When Output is Self, this will be the identity function.

impl Ord for ScopeStackVariable

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ScopeStackVariable

fn eq(&self, other: &ScopeStackVariable) -> 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 PartialOrd for ScopeStackVariable

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<u32> for ScopeStackVariable

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: u32) -> Result<ScopeStackVariable, ()>

Performs the conversion.
