The kind of declaration this is

Variants

Methods

impl Decl

fn absorb(&mut self, other: Self) -> Result<(), Error>

If it is compatible, absorb the new declaration (other) into the old (self); otherwise returns an error.

The rule here is "C-ish", but essentially:

1. Duplicate declarations are no-ops / ignored.
2. If the previous declaration was an FunctionImport or DataImport, then if the subsequent declaration is a corresponding matching Function or Data declaration, it is said to be "upgraded", and forever after is considered a declaration in need of a definition.
3. If the previous declaration was a Function or Data declaration, then a subsequent corresponding FunctionImport or DataImport is a no-op.
4. Anything else is a IncompatibleDeclaration error!

fn is_import(&self) -> bool

Is this an import (function or data) from a shared library?

Trait Implementations

impl Debug for Decl

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Copy for Decl

impl Clone for Decl

fn clone(&self) -> Decl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Decl

fn eq(&self, __arg_0: &Decl) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Decl) -> bool

This method tests for !=.
