Struct Config

pub struct Config<T> {
    pub writer: T,

    pub json_profile_filter: Option<String>,
}

Fields

writer: T

filter: String

chalk_filter: Option<String>

The meaning of CHALK_DEBUG is to tell chalk crates (i.e. chalk-solve, chalk-ir, chalk-recursive) how to filter tracing logs. But now we can only have just one filter, which means we have to merge chalk filter to our main filter (from RA_LOG env).

The acceptable syntax of CHALK_DEBUG is target[span{field=value}]=level. As the value should only affect chalk crates, we’d better manually specify the target. And for simplicity, CHALK_DEBUG only accept the value that specify level.

profile_filter: Option<String>

Filtering syntax, set in a shell:

env RA_PROFILE=*             // dump everything
env RA_PROFILE=foo|bar|baz   // enabled only selected entries
env RA_PROFILE=*@3>10        // dump everything, up to depth 3, if it takes more than 10

json_profile_filter: Option<String>

Filtering syntax, set in a shell:

env RA_PROFILE_JSON=foo|bar|baz
