[−] Expand description

A function being imported from JS

Fields

function: Function

[−] Expand description

The full signature of the function

rust_name: Ident

[−] Expand description

The name rust code will use

js_ret: Option<Type>

[−] Expand description

The type being returned

catch: bool

[−] Expand description

Whether to catch JS exceptions

variadic: bool

[−] Expand description

Whether the function is variadic on the JS side

structural: bool

[−] Expand description

Whether the function should use structural type checking

assert_no_shim: bool

[−] Expand description

Causes the Builder (See cli-support::js::binding::Builder) to error out if it finds itself generating code for a function with this signature

kind: ImportFunctionKind

[−] Expand description

The kind of function being imported

shim: Ident

[−] Expand description

The shim name to use in the generated code. The ‘shim’ is a function that appears in the generated JS as a wrapper around the actual function to import, performing any necessary conversions (EG adding a try/catch to change a thrown error into a Result)

doc_comment: Option<String>

[−] Expand description

The doc comment on this import, if one is provided
