Implementations

impl BashNode

pub fn to_code(&self) -> String

Convert AST node to Bash code string

pub fn depth(&self) -> usize

Calculate AST depth

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

Extract features used in this node

Trait Implementations

impl Clone for BashNode

fn clone(&self) -> BashNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BashNode

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

Formats the value using the given formatter.

impl PartialEq for BashNode

fn eq(&self, other: &BashNode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for BashNode
