Enum svd_expander::WriteConstraintSpec

pub enum WriteConstraintSpec {
    UseEnumeratedValues,
    Range(WriteConstraintRangeSpec),
    WriteAsRead,
    Unconstrained,
}

Defines constraints for writing values to a field.

Variants

UseEnumeratedValues

Only the values in the enumerated values list(s) of the field may be written.

Range(WriteConstraintRangeSpec)

Only integers within the bounds of the range (inclusive) may be written.

WriteAsRead

Only the last-read value can be written.

Unconstrained

There are no constraints on writing to the field. This variant is only constructed in cases where the SVD XML is illogical, for example like this:

<writeConstraint>
  <useEnumeratedValues>false</useEnumeratedValues>
</writeConstraint>

The XML is supposed to contain one of three mutually exclusive options, so it doesn't make sense if the option that it contains is set to false.

Trait Implementations

impl Clone for WriteConstraintSpec

fn clone(&self) -> WriteConstraintSpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WriteConstraintSpec

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

Formats the value using the given formatter.

impl PartialEq<WriteConstraintSpec> for WriteConstraintSpec

fn eq(&self, other: &WriteConstraintSpec) -> bool

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

fn ne(&self, other: &WriteConstraintSpec) -> bool

This method tests for !=.
