Struct cbor::decoder::Config

pub struct Config {
    pub max_len_array: usize,
    pub max_len_bytes: usize,
    pub max_len_text: usize,
    pub max_size_map: usize,
    pub max_nesting: usize,
    pub skip_tags: bool,
    pub check_tags: bool,
}

Config contains various settings which limit resource consumption or enable certain validation options. Please note that the various maximum length/size values apply to an individual element only.

This is mainly to prevent attackers from providing CBOR values whose length is larger than the available memory. In combination the memory consumption can still become large and it is best to limit the incoming bytes to a specific upper bound, e.g. by using std::io::Take.

Fields

max_len_array	Maximum number of array elements
max_len_bytes	Maximum length of a byte string
max_len_text	Maximum length of a string
max_size_map	Maximum number of object fields
max_nesting	Maximum recursion steps when decoder Values
skip_tags	Ignore Tags when decoding Values
check_tags	Validate Value type matches Tag.

Methods

impl Config

fn default() -> Config

• max_len_bytes = 5 MB
• max_len_text = 5 MB
• max_size_map = 1000
• max_nesting = 16
• skip_tags = false
• check_tags = true
