Type: Number
Default: 0
When set to 1, instructs the Rust error repporting to ignore secondary
spans. The problem with secondary spans is that they sometimes appear in
error messages before the main cause of the error, for example: >
1 src/main.rs|98 col 5 error| this function takes 4 parameters but 5
parameters were supplied: defined here
2 src/main.rs|430 col 32 error| this function takes 4 parameters but 5
parameters were supplied: expected 4 parameters
<
This is due to the sorting by line numbers. With this option set to 1,
the 'defined here' span will not be presented.
