Struct DecodeAccumulator 

pub struct DecodeAccumulator { /* private fields */ }

Stateful budget accounting for one decoder invocation.

Implementations

impl DecodeAccumulator

pub const fn limits(&self) -> DecodeLimits

Returns the active decode limits.

pub const fn total_allocated(&self) -> usize

Returns the cumulative allocation accounted so far.

pub fn check_input_len(&self, len: usize) -> Result<(), DecodeError>

Validates the input length before parsing starts.

pub fn check_list_count(&self, count: usize) -> Result<(), DecodeError>

Validates a decoded list item count.

pub fn check_nesting_depth(&self, depth: usize) -> Result<(), DecodeError>

Validates the current nesting depth.

pub fn check_allocation(&mut self, size: usize) -> Result<(), DecodeError>

Accounts for one allocation against the cumulative allocation budget.

Trait Implementations

impl Debug for DecodeAccumulator

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

Formats the value using the given formatter.

impl Eq for DecodeAccumulator

impl PartialEq for DecodeAccumulator

fn eq(&self, other: &DecodeAccumulator) -> 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.
