Struct rustc_serialize::json::Stack

pub struct Stack {
    stack: Vec<InternalStackElement>,
    str_buffer: Vec<u8>,
}

A Stack represents the current position of the parser in the logical structure of the JSON stream.

An example is foo.bar[3].x.

Fields

stack: Vec<InternalStackElement>

str_buffer: Vec<u8>

Implementations

impl Stack

pub fn new() -> Stack

pub fn len(&self) -> usize

Returns The number of elements in the Stack.

pub fn is_empty(&self) -> bool

Returns true if the stack is empty.

pub fn get(&self, idx: usize) -> StackElement<'_>

Provides access to the StackElement at a given index. lower indices are at the bottom of the stack while higher indices are at the top.

pub fn is_equal_to(&self, rhs: &[StackElement<'_>]) -> bool

Compares this stack with an array of StackElement<’_>s.

pub fn starts_with(&self, rhs: &[StackElement<'_>]) -> bool

Returns true if the bottom-most elements of this stack are the same as the ones passed as parameter.

pub fn ends_with(&self, rhs: &[StackElement<'_>]) -> bool

Returns true if the top-most elements of this stack are the same as the ones passed as parameter.

pub fn top(&self) -> Option<StackElement<'_>>

Returns the top-most element (if any).

fn push_key(&mut self, key: String)

fn push_index(&mut self, index: u32)

fn pop(&mut self)

fn last_is_index(&self) -> bool

fn bump_index(&mut self)

Trait Implementations

impl Default for Stack

fn default() -> Stack

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
