Struct RegionBinder

pub struct RegionBinder<T> {
    pub regions: Vector<RegionId, RegionVar>,
    pub skip_binder: T,
}

A value of type T bound by generic parameters. Used in any context where we’re adding generic parameters that aren’t on the top-level item, e.g. for<'a> clauses, trait methods (TODO), GATs (TODO).

Fields

regions: Vector<RegionId, RegionVar>

skip_binder: T

Named this way to highlight accesses to the inner value that might be handling parameters incorrectly. Prefer using helper methods.

Implementations

impl<T> RegionBinder<T>

fn fmt_split<'a, C>(&'a self, ctx: &'a C) -> (String, String)

where C: AstFormatter, T: FmtWithCtx<<C as PushBoundRegions<'a>>::C>,

Format the parameters and contents of this binder and returns the resulting strings.

fn fmt_as_for<'a, C>(&'a self, ctx: &'a C) -> String

where C: AstFormatter, T: FmtWithCtx<<C as PushBoundRegions<'a>>::C>,

Formats the binder as for<params> value.

Trait Implementations

impl<T: Clone> Clone for RegionBinder<T>

fn clone(&self) -> RegionBinder<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for RegionBinder<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for RegionBinder<T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Drive> Drive for RegionBinder<T>

fn drive<V: Visitor>(&self, visitor: &mut V)

impl<T: DriveMut> DriveMut for RegionBinder<T>

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl<T: Hash> Hash for RegionBinder<T>

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<T: PartialEq> PartialEq for RegionBinder<T>

fn eq(&self, other: &RegionBinder<T>) -> 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<T> Serialize for RegionBinder<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
