I've been using abort strategy before to reduce size of the binary in places where I don't need unwinding, but recently I found out about panic_immediate_abort flag after reading the source code of new Windows editor.

github.com/microsoft/edit

Cargo.toml

main

[package]
name = "edit"
version = "1.2.1"
edition = "2024"
rust-version = "1.87"
readme = "README.md"
repository = "https://github.com/microsoft/edit"
homepage = "https://github.com/microsoft/edit"
license = "MIT"
categories = ["text-editors"]

[[bench]]
name = "lib"
harness = false

[features]
debug-latency = []

# We use `opt-level = "s"` as it significantly reduces binary size.
# We could then use the `#[optimize(speed)]` attribute for spot optimizations.
