when executing cargo install gitui, I get:

hi @hoijui thanks for your interest in gitui. any reason to ignore all the info the bug report template asks you to fill in making it easier to help you with your issue?

without any further information my best guess is you try to build with some older rust version. as the readme states: we build using most recent rust

[hoijui]

Then I would recommend updating the edition field
and using 'rust = 1.696` in Cargo.toml.

my rust version is rustc 1.44.0 (49cae5576 2020-06-01).

@hoijui the edition is correct and the rust field did not make it into current cargo yet: https://doc.rust-lang.org/cargo/reference/manifest.html

current supported rust version is: rustc 1.49.0 (e1884a8e3 2020-12-29)
