Struct DeclareGraph

pub struct DeclareGraph { /* private fields */ }

used to declare which overload of function is called, or which possiable type is

Implementations

impl DeclareGraph

pub fn new() -> Self

pub fn new_static_group<I>(&mut self, at: Span, items: I) -> GroupIdx

where I: IntoIterator<Item = Type>,

pub fn build_group(&mut self, gb: GroupBuilder) -> GroupIdx

pub fn apply_filter<T, B>(&mut self, gidx: GroupIdx, defs: &Defs, filter: B)

where T: Types, B: BranchFilter<T>,

pub fn merge_group(&mut self, at: Span, base: GroupIdx, from: GroupIdx)

pub fn declare_type(&mut self, at: Span, gidx: GroupIdx, expect_ty: &TypeDefine)

declare a DeclareGroup’s result is a type

return Err if the type has be declared and isn’t given type, or non of Branch match the given type

pub fn declare_all(&mut self) -> Result<(), Vec<Error>>

pub fn get_type(&self, gidx: GroupIdx) -> &TypeDefine
