Enum UpvarMigrationInfo

enum UpvarMigrationInfo {
    CapturingPrecise {
        source_expr: Option<HirId>,
        var_name: String,
    },
    CapturingNothing {
        use_span: Span,
    },
}

Intermediate format to store the hir_id pointing to the use that resulted in the corresponding place being captured and a String which contains the captured value’s name (i.e: a.b.c)

Variants

CapturingPrecise

We previously captured all of x, but now we capture some sub-path.

Trait Implementations

impl Clone for UpvarMigrationInfo

fn clone(&self) -> UpvarMigrationInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UpvarMigrationInfo

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

Formats the value using the given formatter.

impl Hash for UpvarMigrationInfo

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 UpvarMigrationInfo

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

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

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

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.
