Err

Implementations

Returns a suggested register class to use for this type. This is called when supported_types fails to give a better error message to the user.

Returns a suggested template modifier to use for this type and an example of a register named formatted with it.

Such suggestions are useful if a type smaller than the full register size is used and a modifier can be used to point to the subregister of the correct size.

Returns the default modifier for this register and an example of a register named formatted with it.

This is only needed when the register class can suggest a modifier, so that the user can be shown how to get the default behavior without a warning.

Returns a list of supported types for this register class, each with an options target feature required to use this type.

Returns the list of template modifiers that can be used with this register class.

Returns whether registers in this class can only be used as clobbers and not as inputs/outputs.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
