Struct swc_plugin::ast::Ident
source · [−]pub struct Ident {
pub span: Span,
pub sym: Atom<JsWordStaticSet>,
pub optional: bool,
}
Expand description
A complete identifier with span.
Identifier of swc consists of two parts. The first one is symbol, which is stored using an interned string, JsWord . The second one is SyntaxContext, which can be used to distinguish identifier with same symbol.
Let me explain this with an example.
let a = 5
{
let a = 3;
}
In the code above, there are two variables with the symbol a.
Other compilers typically uses type like Scope
, and store them nested, but
in rust, type like Scope
requires [Arc<Mutexfoo#1
For the example above, after applying resolver pass, it becomes.
let a#1 = 5
{
let a#2 = 3;
}
Thanks to the tag
we attached, we can now distinguish them.
See Id, which is a type alias for this.
This can be used to store all variables in a module to single hash map.
Comparison
While comparing two identifiers, you can use .to_id()
.
HashMap
There’s a type named Id which only contains minimal information to distinguish identifiers.
Fields
span: Span
sym: Atom<JsWordStaticSet>
optional: bool
TypeScript only. Used in case of an optional parameter.
