Struct Selection

Source
pub struct Selection { /* private fields */ }
Expand description

A Selection describes a selector expression x.f. For the declarations:

type T struct{ x int; E } type E struct{} func (e E) m() {} var p *T

the following relations exist:

Selector Kind Recv Obj Type Index Indirect

p.x FieldVal T x int {0} true p.m MethodVal *T m func (e *T) m() {1, 0} true T.m MethodExpr T m func m(_ T) {1, 0} false

Implementations§

Source§

impl Selection

Source

pub fn new( kind: SelectionKind, recv: Option<TypeKey>, obj: ObjKey, indices: Vec<usize>, indirect: bool, objs: &TCObjects, ) -> Selection

Source

pub fn init_type(&mut self, objs: &mut TCObjects)

Source

pub fn kind(&self) -> &SelectionKind

Source

pub fn recv(&self) -> Option<TypeKey>

Source

pub fn obj(&self) -> ObjKey

Source

pub fn typ(&self) -> TypeKey

typ must be called after init is called

Source

pub fn id(&self) -> &String

Source

pub fn indices(&self) -> &Vec<usize>

indices describes the path from x to f in x.f. The last indices entry is the field or method indices of the type declaring f; either:

  1. the list of declared methods of a named type; or
  2. the list of methods of an interface type; or
  3. the list of fields of a struct type.

The earlier indices entries are the indices of the embedded fields implicitly traversed to get from (the type of) x to f, starting at embedding depth 0.

Source

pub fn indirect(&self) -> &bool

Indirect reports whether any pointer indirection was required to get from x to f in x.f.

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