Struct Local

pub struct Local {
    name: LocalName,
    pub span: Option<Span>,
    pub depth: usize,
    pub initialised: bool,
    pub used: bool,
    pub needs_finaliser: bool,
    pub must_thunk: bool,
}

Represents a single local already known to the compiler.

Fields

name: LocalName

Identifier of this local. This is always a statically known value (Nix does not allow dynamic identifier names in locals), or a “phantom” value not accessible by users.

span: Option<Span>

Source span at which this local was declared.

depth: usize

Scope depth of this local.

initialised: bool

Is this local initialised?

used: bool

Is this local known to have been used at all?

needs_finaliser: bool

Does this local need to be finalised after the enclosing scope is completely constructed?

must_thunk: bool

Does this local’s upvalues contain a reference to itself?

Implementations

pub fn name(&self) -> Option<SmolStr>

Retrieve the name of the given local (if available).

pub fn is_ignored(&self) -> bool

Is this local intentionally ignored? (i.e. name starts with _)

pub fn is_used(&self) -> bool

Trait Implementations

impl Debug for Local

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