Function rustc_mir::util::dump_mir

    pass_num: Option<&Display>, 
    pass_name: &str, 
    disambiguator: &Display,

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

If the session is properly configured, dumps a human-readable representation of the mir into:

rustc.node<node_id>.<pass_num>.<pass_name>.<disambiguator>

Output from this function is controlled by passing -Z dump-mir=<filter>, where <filter> takes the following forms:

• all -- dump MIR for all fns, all passes, all everything
• a filter defined by a set of substrings combined with & and | (& has higher precedence). At least one of the |-separated groups must match; an |-separated group matches if all of its &-separated substrings are matched.

Example:

• nll == match if nll appears in the name
• foo & nll == match if foo and nll both appear in the name
• foo & nll | typeck == match if foo and nll both appear in the name or typeck appears in the name.
• foo & nll | bar & typeck == match if foo and nll both appear in the name or typeck and bar both appear in the name.
