Struct Limits

pub struct Limits {
    pub input_file_size: usize,
    pub decompressed_json_size: usize,
}

Protects against denial-of-service attacks via infinite input streams or zip bombs, which would otherwise use up all your memory and crash your machine.

If the limit is exceeded, an error is returned and no further deserialization is attempted.

The default limits are 1 GiB for the input_file_size and 8 MiB for decompressed_json_size.

Note that the decompressed_json_size is only enforced on the level of the serialized JSON, i.e. a string. We do not enforce that serde_json does not consume more memory when deserializing JSON to Rust data structures. Unfortunately Rust does not provide APIs for that.

Fields

input_file_size: usize

decompressed_json_size: usize

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Limits

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Limits

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Limits

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