Lef Key(Word)s

Enumerated “key(word)s” used in LEF parsing and generation.

Unlike typical programming languages, LEF does not really have keywords in the sense of being reserved at all points in the program. Legality of LefKeys is instead context-dependent, more as in a YAML or JSON schema. For example a LefMacro is free to use the name “MACRO” for one of its pins, whereas while during LefLibrary definition, “MACRO” is a key with special meaning.

LEF syntax is case-insensitive. LefKeys are always written in the (conventional) upper-case form, but are parsed case-insensitively.

Trait Implementations

impl Clone for LefKey

fn clone(&self) -> LefKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LefKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LefKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LefKey

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

Formats the value using the given formatter.

impl PartialEq for LefKey

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for LefKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for LefKey

impl Eq for LefKey

impl StructuralPartialEq for LefKey
