Subject: bug#61302: 29.0.60; rust-ts-mode does not show function-invocation on field-properties
Date: Sun, 5 Feb 2023 21:15:28 +0100

[Message part 1 (text/plain, inline)]

Steps to reproduce:

- set font-lock level 4 to enable highlighting of function-invocations
- create a new buffer and activate rust-ts-mode

Try writing a function which invokes functions indirectly trough 
field-properties. Example below:

pub fn should_handle(url: String) -> bool {
    if url.ends_with(".css")
       || url.ends_with(".js")
       || url.ends_with(".png")
       || url.ends_with(".jpg")
    {
        false
    } else {
        true
    }
}

Observe that:

- ends_with() is fontified as a property-access, not as a 
function-invocation.
- (plain function invocation is highlighted as expected though)

From my preliminary inspection of the rust-ts-mode source-code, this 
seems to be because of a very general override later in the file:

rust-ts-mode.el, line 248 or so:

   :language 'rust
   :feature 'property
   :override t
   '((field_identifier) @font-lock-property-face
     (shorthand_field_initializer (identifier) @font-lock-property-face))

Dissabling "override" for this feature fixes the fontification of method 
invocations, but I haven't done enough testing to see if there are other 
unexpected side-effects.
