Enum rustc_borrowck::region_infer::Cause

pub(crate) enum Cause {
    LiveVar(Local, Location),
    DropVar(Local, Location),
}

N.B., the variants in Cause are intentionally ordered. Lower values are preferred when it comes to error messages. Do not reorder willy nilly.

Variants

LiveVar(Local, Location)

point inserted because Local was live at the given Location

DropVar(Local, Location)

point inserted because Local was dropped at the given Location

Trait Implementations

impl Clone for Cause

fn clone(&self) -> Cause

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cause

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

Formats the value using the given formatter.

impl Ord for Cause

fn cmp(&self, other: &Cause) -> 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) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Cause> for Cause

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Cause> for Cause

fn partial_cmp(&self, other: &Cause) -> 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.

impl Copy for Cause

impl Eq for Cause

impl StructuralEq for Cause

impl StructuralPartialEq for Cause

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
