Struct ssa::core::Walker

pub struct Walker<'a> {
    pub node: Node<'a>,
    pub source: &'a str,
}

A pointer to a node of AST tree

Fields

node: Node<'a>

source: &'a str

Methods

impl<'a> Walker<'a>

pub fn new(value: &'a JsonValue, source: &'a str) -> Self

pub fn for_each<Callback>(&self, cb: Callback) where
    Callback: FnMut(Walker<'a>, usize), 

Find all direct childrens of current walker and invoke callback one by one

pub fn for_all<Callback, Filter>(&self, fi: Filter, cb: Callback) where
    Callback: FnMut(Vec<Walker<'a>>),
    Filter: FnMut(&Walker) -> bool, 

Find all direct childrens passing filter and invoke callback one time

pub fn all_break<Callback, Filter>(&self, fi: Filter, cb: Callback) where
    Callback: FnMut(Vec<Walker<'a>>),
    Filter: FnMut(&Walker) -> bool, 

Find all childrens, if children is discovered then stop discovering that path and invoke callback

pub fn all<Callback, Filter>(&self, fi: Filter, cb: Callback) where
    Callback: FnMut(Vec<Walker<'a>>),
    Filter: FnMut(&Walker) -> bool, 

Same as all_break but does ignore any path
