Enum style::properties::declaration_block::DeclarationUpdate

enum DeclarationUpdate {
    None,
    Append,
    UpdateInPlace {
        pos: usize,
    },
    AppendAndRemove {
        pos: usize,
    },
}

An enum describes how a declaration should update the declaration block.

Variants

None

The given declaration doesn’t update anything.

Append

The given declaration is new, and should be append directly.

UpdateInPlace

The given declaration can be updated in-place at the given position.

AppendAndRemove

pos: usize

The given declaration cannot be updated in-place, and an existing one needs to be removed at the given position.

Trait Implementations

impl Clone for DeclarationUpdate

fn clone(&self) -> DeclarationUpdate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeclarationUpdate

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

Formats the value using the given formatter.

impl PartialEq<DeclarationUpdate> for DeclarationUpdate

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

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

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

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