Struct MarkerRefinement

pub struct MarkerRefinement {
    on_argument: TinyBitSet,
    on_return: bool,
}

Refinements in the marker targeting. The default (no refinement provided) is on_argument == vec![] and on_return == false, which is also what is returned from Self::empty.

Fields

on_argument: TinyBitSet

on_return: bool

Implementations

impl MarkerRefinement

pub fn empty() -> Self

The default, empty aggregate refinement Self { on_argument: vec![], on_return: false }

pub fn merge_kind(self, k: MarkerRefinementKind) -> Result<Self, String>

Merge the aggregate refinement with another discovered refinement and check that they do not overwrite each other.

pub fn on_argument(&self) -> TinyBitSet

Get the refinements on arguments

pub fn on_return(&self) -> bool

Is this refinement targeting the return value?

pub fn on_self(&self) -> bool

True if this refinement is empty, i.e. the annotation is targeting the item itself.

Trait Implementations

impl Clone for MarkerRefinement

fn clone(&self) -> MarkerRefinement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MarkerRefinement

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for MarkerRefinement

fn decode(__decoder: &mut __D) -> Self

impl<'de> Deserialize<'de> for MarkerRefinement

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MarkerRefinement

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

Formats the value using the given formatter.

impl<__E: SpanEncoder> Encodable<__E> for MarkerRefinement

fn encode(&self, __encoder: &mut __E)

impl Ord for MarkerRefinement

fn cmp(&self, other: &MarkerRefinement) -> 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 MarkerRefinement

fn eq(&self, other: &MarkerRefinement) -> 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 MarkerRefinement

fn partial_cmp(&self, other: &MarkerRefinement) -> 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 Serialize for MarkerRefinement

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
