Implementations

impl<'a> ProjectedUserTypesNode<'a>

pub(crate) fn push_user_types( &'a self, base_types: SmallVec<[UserTypeAnnotationIndex; 4]>, ) -> Self

fn maybe_push(&'a self, op_fn: impl FnOnce() -> ProjectedUserTypesOp) -> Self

Push another projection op onto the chain, but only if it is already non-empty.

pub(crate) fn index(&'a self) -> Self

pub(crate) fn subslice(&'a self, from: u64, to: u64) -> Self

pub(crate) fn deref(&'a self) -> Self

pub(crate) fn leaf(&'a self, field: FieldIdx) -> Self

pub(crate) fn variant( &'a self, adt_def: AdtDef<'_>, variant: VariantIdx, field: FieldIdx, ) -> Self

fn iter_ops_reversed(&'a self) -> impl Iterator<Item = &'a ProjectedUserTypesOp>

Traverses the chain of nodes to yield each op in the chain. Because this walks from child node to parent node, the ops are naturally yielded in “reverse” order.

pub(crate) fn build_user_type_projections( &self, ) -> Option<Box<UserTypeProjections>>

Assembles this chain of user-type projections into a proper data structure.

Trait Implementations

impl<'a> Debug for ProjectedUserTypesNode<'a>

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

Formats the value using the given formatter.

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.
