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.

Trait Implementations

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Feeds this value into the given Hasher. Read more
Feeds a slice of this type into the given Hasher. Read more
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
This method returns an ordering between self and other values if one exists. Read more
This method tests less than (for self and other) and is used by the < operator. Read more
This method tests less than or equal to (for self and other) and is used by the <= operator. Read more
This method tests greater than (for self and other) and is used by the > operator. Read more
This method tests greater than or equal to (for self and other) and is used by the >= operator. Read more

Auto Trait Implementations

Blanket Implementations

Gets the TypeId of self. Read more
Immutably borrows from an owned value. Read more
Mutably borrows from an owned value. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

The resulting type after obtaining ownership.
Creates owned data from borrowed data, usually by cloning. Read more
Uses borrowed data to replace owned data, usually by cloning. Read more
The type returned in the event of a conversion error.
Performs the conversion.
The type returned in the event of a conversion error.
Performs the conversion.

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.
