Struct FollowConfig 

pub struct FollowConfig {
    pub ignore: Vec<String>,
    pub transitive_min: usize,
    pub aliases: HashMap<String, Vec<String>>,
    pub max_depth: Option<usize>,
}

[follow] section of Config.

Fields

ignore: Vec<String>

Inputs to skip during follow analysis.

See Self::is_ignored for the matching rules.

transitive_min: usize

Minimum number of transitive references required before a shared nested input is promoted to top-level. 0 disables transitive deduplication.

aliases: HashMap<String, Vec<String>>

Alias mappings: canonical name to alternative names. For example, nixpkgs = ["nixpkgs-lib"] lets nixpkgs-lib follow nixpkgs.

max_depth: Option<usize>

Maximum depth of follows declarations to write.

None (the default) writes follows at every depth the lockfile graph supports. Some(n) caps the depth: Some(1) writes only parent.nested.follows = "target", Some(2) also writes deeper paths such as parent.middle.grandchild.follows = "target".

Implementations

impl FollowConfig

pub fn is_ignored(&self, path: &str, name: &str) -> bool

True if the input at path (e.g. crane.nixpkgs) with simple name (e.g. nixpkgs) is in Self::ignore.

Entries containing a . match the full dotted path. Bare entries match by name across all parents.

pub fn resolve_alias(&self, name: &str) -> Option<&str>

Canonical name name is an alias of, or None if no alias applies.

pub fn can_follow(&self, nested_name: &str, top_level_name: &str) -> bool

True if nested_name may follow top_level_name (direct match or via Self::aliases).

pub fn transitive_min(&self) -> usize
