Struct CallTree 

#[non_exhaustive]
pub struct CallTree {
    pub direction: Direction,
    pub depth: usize,
    pub rows: Vec<CallRow>,
    pub methods: usize,
    pub truncated: bool,
    pub pruned: usize,
    pub reached: Option<usize>,
    pub errors: Vec<String>,

}

Result of Engine::call_graph.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

direction: Direction

The direction walked.

depth: usize

The depth asked for.

rows: Vec<CallRow>

The tree, one row per line in depth-first order.

methods: usize

Distinct methods discovered (roots included).

truncated: bool

More callers / callees exist than max_nodes allowed.

pruned: usize

Methods left out because their code matches CallQuery::unless.

reached: Option<usize>

With CallQuery::from: the distinct from methods reached.

errors: Vec<String>

DEX entries that could not be loaded or searched.

notes: Vec<String>

What the conditions left out on purpose (crate::RefSummary::notes).

Implementations

impl CallTree

pub fn lines(&self) -> Vec<String>

One line per row: indentation and the depth number, an arrow (<- caller, -> callee), the signature and flags: [no body] (defined in no DEX of the APK, e.g. a framework method), [services.jar] (in a program of several archives: those defining it) and (repeated) (expanded elsewhere in the tree).

pub fn footer(&self) -> String

Footer comment summarising the walk.

Trait Implementations

impl Clone for CallTree

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CallTree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
