Struct brane_dsl::symbol_table::ClassEntry

pub struct ClassEntry {
    pub signature: ClassSignature,
    pub symbol_table: Rc<RefCell<SymbolTable>>,
    pub package_name: Option<String>,
    pub package_version: Option<Version>,
    pub index: usize,
    pub range: TextRange,
}

Defines a class entry (i.e., custom type) within the SymbolTable.

Fields

signature: ClassSignature

The signature of the class (i.e., its name).

symbol_table: Rc<RefCell<SymbolTable>>

References the SymbolTable where the nested declarations are present. This is used to resolve projection on the class.

package_name: Option<String>

If populated, then this Class was defined in a package with the given name.

package_version: Option<Version>

If set to non-zero, then this function is imported from a package with the given version.

index: usize

The index in the workflow buffer of this class.

range: TextRange

Points to the entire class definition (or import).

Implementations

impl ClassEntry

pub fn from_builtin( signature: ClassSignature, symbol_table: Rc<RefCell<SymbolTable>>, range: TextRange, ) -> Self

Creates a ClassEntry as if it was defined as a builtin type.

Arguments

• signature: The signature of the ClassEntry (contains its name).
• symbol_table: The nested SymbolTable that this Class uses to identify its fields.
• range: The TextRange that points to the definition itself.

Returns

A new ClassEntry that has no package set, but does have type information populated.

pub fn from_def( signature: ClassSignature, symbol_table: Rc<RefCell<SymbolTable>>, range: TextRange, ) -> Self

Creates a ClassEntry as if it was defined in the source text.

Arguments

• signature: The signature of the ClassEntry (contains its name).
• symbol_table: The nested SymbolTable that this Class uses to identify its fields.
• range: The TextRange that points to the definition itself.

Returns

A new ClassEntry that has no package set, but does have type information populated.

pub fn from_import<S: Into<String>>( signature: ClassSignature, symbol_table: Rc<RefCell<SymbolTable>>, package: S, package_version: Version, range: TextRange, ) -> Self

Creates a ClassEntry as if it was imported by the given package.

Generic arguments

• S: The String-like type of the package.

Arguments

• name: The name of the ClassEntry.
• symbol_table: The nested SymbolTable that this Class uses to identify its fields.
• package: The name of the package to which this class belongs.
• package_version: The version of the package to which this function belongs.
• range: The TextRange that points to the definition itself (i.e., the import statement).

Returns

A new ClassEntry that has the given package set and is defined as not having methods.
