Struct GroupMap 

pub struct GroupMap {
    pub rules: Vec<GroupRule>,
    pub strict: bool,
}

Compiled set of grouping rules. Built once per run from Options.group_file.

Fields

rules: Vec<GroupRule>

strict: bool

Implementations

impl GroupMap

pub fn from_file(path: &Path, strict: bool) -> Result<Self, GroupParseError>

Read <repo_root>/<file> (or any absolute path) and parse it. Strict mode is supplied separately from the Options.strict_grouping field; the file format doesn’t carry it.

Errors

Returns GroupParseError on I/O failure, missing separator, empty pattern/name, or invalid regex.

pub fn parse(text: &str, strict: bool) -> Result<Self, GroupParseError>

Parse the group-file text format.

Lines:

• Blank lines are skipped.
• #-prefix lines are treated as comments and skipped.
• Other lines must contain => separating LHS from RHS.
• LHS leading ^ → treat as full regex (with lookaround support).
• LHS without ^ → escape as literal, prefix-anchor + trailing slash: src/foo → ^src/foo/ so it matches src/foo/bar.rs but not src/foobar.rs.

Errors

See GroupParseError.

pub fn map_entity(&self, path: &str) -> Option<&str>

First-match-wins lookup. Returns the logical group name for the path or None if no rule matches.

Trait Implementations
