Implementations

impl ModuleGraph

pub fn new() -> Self

pub fn get_node( &self, path: &NormalizedPathBuf ) -> Option<&Node<NormalizedPathBuf, ()>>

pub fn depends_on( &self, path: &NormalizedPathBuf, target: &NormalizedPathBuf ) -> bool

if path depends on target, returns true, else false. if path not found, returns false

pub fn children(&self, path: &NormalizedPathBuf) -> Set<NormalizedPathBuf>

(usually) path is not contained

pub fn ancestors(&self, path: &NormalizedPathBuf) -> Set<NormalizedPathBuf>

# a.er
b = import "b"

-> a: child, b: parent

pub fn add_node_if_none(&mut self, path: &NormalizedPathBuf)

pub fn inc_ref( &mut self, referrer: &NormalizedPathBuf, depends_on: NormalizedPathBuf ) -> Result<(), IncRefError>

returns Err (and do nothing) if this operation makes a cycle

pub fn iter(&self) -> impl Iterator<Item = &Node<NormalizedPathBuf, ()>>

pub fn sorted(self) -> Result<Self, TopoSortError>

pub fn sort(&mut self) -> Result<(), TopoSortError>

pub fn remove(&mut self, path: &NormalizedPathBuf)

Do not erase relationships with modules that depend on path

pub fn rename_path(&mut self, old: &NormalizedPathBuf, new: NormalizedPathBuf)

pub fn initialize(&mut self)

pub fn display_parents( &self, lev: usize, id: &NormalizedPathBuf, appeared: &mut Set<NormalizedPathBuf> ) -> String

pub fn display(&self) -> String
