Struct tvix_eval::compiler::scope::Local

pub struct Local {
    name: LocalName,
    pub span: Span,

Expand description

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: 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§

source

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