pub struct Attributes { /* private fields */ }
Expand description

Attributes associated with a specific IR structure.

Implementations

Add a new attribute

Get the value associated with an attribute key

Check if an attribute key has been set

Returns true if there are no attributes

Remove attribute with the name key

self copys (i.e., assigns the same values) the attributes in other. However, we only copy attributes in keys (i.e.. we don’t copy all attributes in other, only the ones that we specify). If a key is not present in other, then we ignore that key. Example: suppose self: A->10, B->5 other: A->15, C->5 keys: A, D Then self gets: A->15 B->5. (D is ignored since it’s not present in other and C is ignored since it’s not keys.)

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more

Checks if this value is equivalent to the given key. Read more
Compare self to key and return true if they are equal.

Returns the argument unchanged.
