I want to use
cargo build --message-format=short or
cargo check --message-format=short
as default setting

Might be worth filing a feature request (couldn't find one) for a CARGO_MESSAGE_FORMAT environment variable and/or a configuration option under [term] (which'd be the two most obvious places to put global configuration of the message format IMO).

Understand Better + Faster

Cursor and Other VibeCoding IDE use cargo build in the terminal , but the default message is format for humanreading ,

  1. it take more tokens
  2. it is hard to understand for Ai , for example

For human

  warning: unused variable: `x`
  |       --> src\main.rs:6:9
  | 6 |  let x : i32 =2 ; 
  |            ^ help: if this is intentional, prefix it with an underscore: `_x` 
  |       = note: `#[warn(unused_variables)]` (part of `#[warn(unused)]`) on by default

For Ai

warning: unused variable: `x` --> src\main.rs:6:9  | 6 |     let x : i32  =2 ;   |         ^ help: if this is intentional, prefix it with an underscore: `_x`  |  = note: `#[warn(unused_variables)]` (part of `#[warn(unused)]`) on by default

there are many useless words like | ^ --> and many space

So it is hard to understanding and take more tokens
