Implementations

impl Declaration

pub fn declarations(&self) -> Vec<EntityId>

impl Declaration

pub fn is_allowed_in_context(&self, parent: &AnyEntKind<'_>) -> bool

Returns whether the declaration denoted by self is allowed in the given context. For example, within an architecture, only constants, signals and shared variables are allowed, variables are not.

Conforming example:

architecture arch of ent is
    signal foo : bit;
begin
end arch;

Non-Conforming example:

architecture arch of ent is
    variable foo : bit;
begin
end arch;

The context is given by the parent element of the declaration.

impl Declaration

pub fn describe(&self) -> &'static str

Trait Implementations

impl Clone for Declaration

fn clone(&self) -> Declaration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Declaration

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

Formats the value using the given formatter.

impl PartialEq for Declaration

fn eq(&self, other: &Declaration) -> 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 Search for Declaration

fn search( &self, ctx: &dyn TokenAccess, searcher: &mut impl Searcher, ) -> SearchResult

impl StructuralPartialEq for Declaration
