Struct rustc_hir_typeck::upvar::MigrationWarningReason

struct MigrationWarningReason {
    auto_traits: Vec<&'static str>,
    drop_order: bool,
}

Reasons that we might issue a migration warning.

Fields

auto_traits: Vec<&'static str>

When we used to capture x in its entirety, we implemented the auto-trait(s) in this vec, but now we don’t.

drop_order: bool

When we used to capture x in its entirety, we would execute some destructors at a different time.

Implementations

impl MigrationWarningReason

fn migration_message(&self) -> String

Trait Implementations

impl Clone for MigrationWarningReason

fn clone(&self) -> MigrationWarningReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationWarningReason

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

Formats the value using the given formatter.

impl Default for MigrationWarningReason

fn default() -> MigrationWarningReason

Returns the “default value” for a type.

impl Hash for MigrationWarningReason

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 Ord for MigrationWarningReason

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<MigrationWarningReason> for MigrationWarningReason

fn eq(&self, other: &MigrationWarningReason) -> 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<MigrationWarningReason> for MigrationWarningReason

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

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.
