Struct Limits 

pub struct Limits {
    pub max_nesting_depth: usize,
    pub max_block_size: usize,
    pub max_items: usize,
    pub max_memory: usize,
    pub max_string_length: usize,
}

Resource limits for decoder operations.

Fields

max_nesting_depth: usize

Maximum nesting depth for objects/arrays (default: 128).

max_block_size: usize

Maximum size of a single block in bytes (default: 64 MiB).

max_items: usize

Maximum number of items in a single array or object (default: 1M).

max_memory: usize

Maximum total memory allocation for a single decode session (default: 256 MiB).

max_string_length: usize

Maximum string length in bytes (default: 16 MiB).

Implementations

impl Limits

pub fn strict() -> Self

Restrictive limits suitable for untrusted input.

pub fn unlimited() -> Self

No limits — for trusted data only.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Limits

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

Formats the value using the given formatter.

impl Default for Limits

fn default() -> Self

Returns the “default value” for a type.
