error[E0599]: no method named `is_none_or` found for enum `Option` in the current scope]


Answer: Issue: The build is failing because the Rust code in the skrifa crate is using a method is_none_or on an Option that doesn't exist in the version of Rust being used for the build (Rust 1.79.0). The error message suggests using is_none instead.

The is_none_or method was probably introduced in a later version of Rust. The code in ../../third_party/rust/chromium_crates_io/vendor/skrifa-0.29.2/src/glyph_name.rs at line 97 is likely checking if an Option is either None or contains an empty string.
Resolution: There are 2 options to resolve the build failure:

1. Update rust compiler to newer version 1.86
2. The is_none_or method was probably introduced in a later version of Rust. The code in ../../third_party/rust/chromium_crates_io/vendor/skrifa-0.29.2/src/glyph_name.rs at line 97 is checking if an Option is either None or contains an empty string.

Modify that line of code like following: 
Original code:
if name.as_ref().is_none_or(|s| s.is_empty()) { 

Fixed code:
if name.is_none() || name.as_ref().map_or(false, |s| s.is_empty()) {
