Struct Flow 

pub struct Flow {
    pub steps: Vec<Step>,
}

The ordered call/control skeleton of one callable body.

Fields

steps: Vec<Step>

Top-level steps in source order.

Implementations

impl Flow

pub fn new(steps: Vec<Step>) -> Self

Wrap a list of steps.

pub fn is_empty(&self) -> bool

true when the body makes no calls at all.

pub fn calls(&self) -> impl Iterator<Item = &Call>

Every call in depth-first source order.

pub fn call_count(&self) -> usize

Number of calls in the whole tree.

pub fn depth(&self) -> usize

Maximum nesting depth of control fragments (0 for a flat sequence).

Trait Implementations

impl Clone for Flow

fn clone(&self) -> Self

Returns a duplicate of the value.

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

impl Debug for Flow

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

Formats the value using the given formatter.

impl Default for Flow

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Flow

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,
